And at the last He will take His stand upon the earth.

“Now behold, today I am going the way of all the earth, and you know in all your hearts and in all your souls that not one word of all the good words which the Lord your God has promised concerning you has failed; all have been fulfilled for you, not one of them has failed.

My heart will not fear;
Though war arise against me,
Even in this I am confident.

For she thought, “If I just touch His clothing, I will get well.”

for she had been saying to herself, “If I only touch His outer robe, I will be healed.”

it seemed fitting for me as well, [and so I have decided] after having carefully searched out and investigated all the events accurately, from the very beginning, to write an orderly account for you, most excellent Theophilus; so that you may know the exact truth about the things you have been taught [that is, the history and doctrine of the faith].

For I am convinced [and continue to be convinced—beyond any doubt] that neither death, nor life, nor angels, nor principalities, nor things present and threatening, nor things to come, nor powers, nor height, nor depth, nor any other created thing, will be able to separate us from the [unlimited] love of God, which is in Christ Jesus our Lord.

But more than that, I count everything as loss compared to the priceless privilege and supreme advantage of knowing Christ Jesus my Lord [and of growing more deeply and thoroughly acquainted with Him—a joy unequaled]. For His sake I have lost everything, and I consider it all garbage, so that I may gain Christ,

We know [with confidence] that anyone born of God does not habitually sin; but He (Jesus) who was born of God [carefully] keeps and protects him, and the evil one does not touch him. We know [for a fact] that we are of God, and the whole world [around us] lies in the power of the evil one [opposing God and His precepts]. And we [have seen and] know [by personal experience] that the Son of God has [actually] come [to this world], and has given us understanding and insight so that we may [progressively and personally] know Him who is true; and we are in Him who is true—in His Son Jesus Christ. This is the true God and eternal life.

so that by two unchangeable things [His promise and His oath] in which it is impossible for God to lie, we who have fled [to Him] for refuge would have strong encouragement and indwelling strength to hold tightly to the hope set before us.

“God is not a man, that He should lie,
Nor a son of man, that He should repent.
Has He said, and will He not do it?
Or has He spoken and will He not make it good and fulfill it?

“Behold, I have received His command to bless [Israel].
He has blessed, and I cannot reverse it.

Therefore know [without any doubt] and understand that the Lord your God, He is God, the faithful God, who is keeping His covenant and His [steadfast] lovingkindness to a thousand generations with those who love Him and keep His commandments; but repays those who hate Him to their faces, by destroying them; He will not hesitate with him who hates Him, He will repay him to his face.

“For I proclaim the name [and presence] of the Lord;
Ascribe greatness and honor to our God!

“The Rock! His work is perfect,
For all His ways are just;
A God of faithfulness without iniquity (injustice),
Just and upright is He.

And now, O Lord God, You are God, and Your words are truth, and You have promised this good thing to Your servant.

As for God, His way is blameless.
The word of the Lord is tested [it is perfect, it is faultless];
He is a shield to all who take refuge in Him.

For who is God, but the Lord?
Or who is a rock, except our God,

“Trust [confidently] in the Lord forever [He is your fortress, your shield, your banner],
For the Lord God is an everlasting Rock [the Rock of Ages].

Indeed men swear [an oath] by one greater than themselves, and with them [in all disputes] the oath serves as confirmation [of what has been said] and is an end of the dispute. In the same way God, in His desire to show to the heirs of the promise the unchangeable nature of His purpose, intervened and guaranteed it with an oath, so that by two unchangeable things [His promise and His oath] in which it is impossible for God to lie, we who have fled [to Him] for refuge would have strong encouragement and indwelling strength to hold tightly to the hope set before us. read more.
This hope [this confident assurance] we have as an anchor of the soul [it cannot slip and it cannot break down under whatever pressure bears upon it]—a safe and steadfast hope that enters within the veil [of the heavenly temple, that most Holy Place in which the very presence of God dwells],

For I tell you that Christ has become a servant and a minister to the circumcision (Jews) on behalf of God’s truth, to confirm and verify the promises made to the fathers,

Then Gideon said to God, “If You are going to rescue Israel through me, as You have spoken, behold, I will put a fleece of [freshly sheared] wool on the threshing floor. If there is dew only on the fleece, and it is dry on all the ground [around it], then I will know that You will rescue Israel through me, as You have said.” And it was so. When he got up early the next morning and squeezed the dew out of the fleece, he wrung from it a bowl full of water. read more.
Then Gideon said to God, “Do not let your anger burn against me, so that I may speak once more. Please let me make a test once more with the fleece; now let only the fleece be dry, and let there be dew on all the ground.” God did so that night; for it was dry only on the fleece, and there was dew on all the ground [around it].

So Moses and Aaron said to all Israel, “At evening you shall know that the Lord has brought you out of the land of Egypt, and in the morning you will see the glory of the Lord, for He hears your murmurings against the Lord. What are we, that you murmur and rebel against us?” Moses said, “This will happen when the Lord gives you meat to eat in the evening, and in the morning [enough] bread to be fully satisfied, because the Lord has heard your murmurings against Him; for what are we? Your murmurings are not against us, but against the Lord.”

Moses said to the Lord, “See, You say to me, ‘Bring up this people,’ but You have not let me know whom You will send with me. Yet You have said, ‘I know you by name, and you have also found favor in My sight.’ Now therefore, I pray you, if I have found favor in Your sight, let me know Your ways so that I may know You [becoming more deeply and intimately acquainted with You, recognizing and understanding Your ways more clearly] and that I may find grace and favor in Your sight. And consider also, that this nation is Your people.” And the Lord said, “My presence shall go with you, and I will give you rest [by bringing you and the people into the promised land].” read more.
And Moses said to Him, “If Your presence does not go [with me], do not lead us up from here. For how then can it be known that Your people and I have found favor in Your sight? Is it not by Your going with us, so that we are distinguished, Your people and I, from all the [other] people on the face of the earth?” The Lord said to Moses, “I will also do this thing that you have asked; for you have found favor (lovingkindness, mercy) in My sight and I have known you [personally] by name.” Then Moses said, “Please, show me Your glory!” And God said, “I will make all My goodness pass before you, and I will proclaim the Name of the Lord before you; for I will be gracious to whom I will be gracious, and will show compassion (lovingkindness) on whom I will show compassion.” But He said, “You cannot see My face, for no man shall see Me and live!” Then the Lord said, “Behold, there is a place beside Me, and you shall stand there on the rock; and while My glory is passing by, I will put you in a cleft of the rock and protectively cover you with My hand until I have passed by. Then I will take away My hand and you shall see My back; but My face shall not be seen.”

Joshua said to the Israelites, “Come here, and listen to the words of the Lord your God.” Joshua said, “By this you shall know that the living God is among you, and that He will, without fail, drive out from before you the Canaanite, the Hittite, the Hivite, the Perizzite, the Girgashite, the Amorite, and the Jebusite. Behold, the ark of the covenant of the Lord of all the earth is crossing over ahead of you [leading the way] into the Jordan. read more.
So now take for yourselves twelve men from the tribes of Israel, one man from each tribe. When the soles of the feet of the priests who carry the ark of the Lord, the Lord of all the earth, [come to] rest in the waters of the Jordan, the waters of the Jordan flowing down from above will be cut off, and they will stand in one mass [of water].”

At the time of the offering of the evening sacrifice, Elijah the prophet approached [the altar] and said, “O Lord, the God of Abraham, Isaac, and Israel (Jacob), let it be known today that You are God in Israel and that I am Your servant and that I have done all these things at Your word. Answer me, O Lord, answer me, so that this people may know that You, O Lord, are God, and that You have turned their hearts back [to You].” Then the fire of the Lord fell and consumed the burnt offering and the wood, and even the stones and the dust; it also licked up the water in the trench. read more.
When all the people saw it, they fell face downward; and they said, “The Lord, He is God! The Lord, He is God!”

that Jesus, knowing that the Father had put everything into His hands, and that He had come from God and was [now] returning to God,

And He began to teach them that the Son of Man must [of necessity] suffer many things and be rejected [as the Messiah] by the elders and the chief priests and the scribes, and must be put to death, and after three days rise [from death to life].

From that time on Jesus began to show His disciples [clearly] that He must go to Jerusalem, and endure many things at the hands of the elders and the chief priests and scribes (Sanhedrin, Jewish High Court), and be killed, and be raised [from death to life] on the third day.

saying, “The Son of Man must suffer many things and be rejected [as the Messiah] by the elders and chief priests and scribes (Sanhedrin, Jewish High Court), and be put to death, and on the third day be raised up [from death to life].”

I am the Good Shepherd, and I know [without any doubt those who are] My own and My own know Me [and have a deep, personal relationship with Me]— even as the Father knows Me and I know the Father—and I lay down My [very own] life [sacrificing it] for the benefit of the sheep. I have other sheep [beside these] that are not of this fold. I must bring those also, and they will listen to My voice and pay attention to My call, and they will become one flock with one Shepherd. read more.
For this reason the Father loves Me, because I lay down My [own] life so that I may take it back. No one takes it away from Me, but I lay it down voluntarily. I am authorized and have power to lay it down and to give it up, and I am authorized and have power to take it back. This command I have received from My Father.”

Jesus said to him, “I am the [only] Way [to God] and the [real] Truth and the [real] Life; no one comes to the Father but through Me. If you had [really] known Me, you would also have known My Father. From now on you know Him, and have seen Him.” Philip said to Him, “Lord, show us the Father and then we will be satisfied.” read more.
Jesus said to him, “Have I been with you for so long a time, and you do not know Me yet, Philip, nor recognize clearly who I am? Anyone who has seen Me has seen the Father. How can you say, ‘Show us the Father?’ Do you not believe that I am in the Father, and the Father is in Me? The words I say to you I do not say on My own initiative or authority, but the Father, abiding continually in Me, does His works [His attesting miracles and acts of power]. Believe Me that I am in the Father and the Father is in Me; otherwise believe [Me] because of the [very] works themselves [which you have witnessed].

This is why I suffer as I do. Still, I am not ashamed; for I know Him [and I am personally acquainted with Him] whom I have believed [with absolute trust and confidence in Him and in the truth of His deity], and I am persuaded [beyond any doubt] that He is able to guard that which I have entrusted to Him until that day [when I stand before Him].

Simon Peter replied, “You are the Christ (the Messiah, the Anointed), the Son of the living God.”

And He asked them, “But who do you say that I am?” Peter replied to Him, “You [in contrast to the others] are the Christ (the Messiah, the Anointed).”

And He said to them, “But who do you say that I am?” Peter replied, “The Christ (the Messiah, the Anointed) of God!”

She said to Him, “Yes, Lord; I have believed and continue to believe that You are the Christ (the Messiah, the Anointed), the Son of God, He who was [destined and promised] to come into the world [and it is for You that the world has waited].”

Thomas answered Him, “My Lord and my God!” Jesus said to him, “Because you have seen Me, do you now believe? Blessed [happy, spiritually secure, and favored by God] are they who did not see [Me] and yet believed [in Me].”

This is the same disciple who is testifying to these things and has recorded them; and we know [without any doubt] that his testimony is true.

Now it is God who establishes and confirms us [in joint fellowship] with you in Christ, and who has anointed us [empowering us with the gifts of the Spirit]; it is He who has also put His seal on us [that is, He has appropriated us and certified us as His] and has given us the [Holy] Spirit in our hearts as a pledge [like a security deposit to guarantee the fulfillment of His promise of eternal life].

Therefore, [inheriting] the promise depends entirely on faith [that is, confident trust in the unseen God], in order that it may be given as an act of grace [His unmerited favor and mercy], so that the promise will be [legally] guaranteed to all the descendants [of Abraham]—not only for those [Jewish believers] who keep the Law, but also for those [Gentile believers] who share the faith of Abraham, who is the [spiritual] father of us all—

What then shall we say to all these things? If God is for us, who can be [successful] against us? He who did not spare [even] His own Son, but gave Him up for us all, how will He not also, along with Him, graciously give us all things? Who will bring any charge against God’s elect (His chosen ones)? It is God who justifies us [declaring us blameless and putting us in a right relationship with Himself]. read more.
Who is the one who condemns us? Christ Jesus is the One who died [to pay our penalty], and more than that, who was raised [from the dead], and who is at the right hand of God interceding [with the Father] for us. Who shall ever separate us from the love of Christ? Will tribulation, or distress, or persecution, or famine, or nakedness, or danger, or sword? Just as it is written and forever remains written,

“For Your sake we are put to death all day long;
We are regarded as sheep for the slaughter.” Yet in all these things we are more than conquerors and gain an overwhelming victory through Him who loved us [so much that He died for us]. For I am convinced [and continue to be convinced—beyond any doubt] that neither death, nor life, nor angels, nor principalities, nor things present and threatening, nor things to come, nor powers, nor height, nor depth, nor any other created thing, will be able to separate us from the [unlimited] love of God, which is in Christ Jesus our Lord.

I am convinced and confident of this very thing, that He who has begun a good work in you will [continue to] perfect and complete it until the day of Christ Jesus [the time of His return].

so that by two unchangeable things [His promise and His oath] in which it is impossible for God to lie, we who have fled [to Him] for refuge would have strong encouragement and indwelling strength to hold tightly to the hope set before us. This hope [this confident assurance] we have as an anchor of the soul [it cannot slip and it cannot break down under whatever pressure bears upon it]—a safe and steadfast hope that enters within the veil [of the heavenly temple, that most Holy Place in which the very presence of God dwells],

By this we know [with confident assurance] that we abide in Him and He in us, because He has given to us His [Holy] Spirit.

And this is how we know [daily, by experience] that we have come to know Him [to understand Him and be more deeply acquainted with Him]: if we habitually keep [focused on His precepts and obey] His commandments (teachings). Whoever says, “I have come to know Him,” but does not habitually keep [focused on His precepts and obey] His commandments (teachings), is a liar, and the truth [of the divine word] is not in him. But whoever habitually keeps His word and obeys His precepts [and treasures His message in its entirety], in him the love of God has truly been perfected [it is completed and has reached maturity]. By this we know [for certain] that we are in Him: read more.
whoever says he lives in Christ [that is, whoever says he has accepted Him as God and Savior] ought [as a moral obligation] to walk and conduct himself just as He walked and conducted Himself.

“So everyone who hears these words of Mine and acts on them, will be like a wise man [a far-sighted, practical, and sensible man] who built his house on the rock. And the rain fell, and the floods and torrents came, and the winds blew and slammed against that house; yet it did not fall, because it had been founded on the rock. And everyone who hears these words of Mine and does not do them, will be like a foolish (stupid) man who built his house on the sand. read more.
And the rain fell, and the floods and torrents came, and the winds blew and slammed against that house; and it fell—and great and complete was its fall.”

“Why do you call Me, ‘Lord, Lord,’ and do not practice what I tell you? Everyone who comes to Me and listens to My words and obeys them, I will show you whom he is like: he is like a [far-sighted, practical, and sensible] man building a house, who dug deep and laid a foundation on the rock; and when a flood occurred, the torrent burst against that house and yet could not shake it, because it had been securely built and founded on the rock. read more.
But the one who has [merely] heard and has not practiced [what I say], is like a [foolish] man who built a house on the ground without any foundation, and the torrent burst against it; and it immediately collapsed, and the ruin of that house was great.”

This is the [remarkable degree of] confidence which we [as believers are entitled to] have before Him: that if we ask anything according to His will, [that is, consistent with His plan and purpose] He hears us. And if we know [for a fact, as indeed we do] that He hears and listens to us in whatever we ask, we [also] know [with settled and absolute knowledge] that we have [granted to us] the requests which we have asked from Him.

“Ask and keep on asking and it will be given to you; seek and keep on seeking and you will find; knock and keep on knocking and the door will be opened to you. For everyone who keeps on asking receives, and he who keeps on seeking finds, and to him who keeps on knocking, it will be opened. Or what man is there among you who, if his son asks for bread, will [instead] give him a stone? read more.
Or if he asks for a fish, will [instead] give him a snake? If you then, evil (sinful by nature) as you are, know how to give good and advantageous gifts to your children, how much more will your Father who is in heaven [perfect as He is] give what is good and advantageous to those who keep on asking Him.

“So I say to you, ask and keep on asking, and it will be given to you; seek and keep on seeking, and you will find; knock and keep on knocking, and the door will be opened to you. For everyone who keeps on asking [persistently], receives; and he who keeps on seeking [persistently], finds; and to him who keeps on knocking [persistently], the door will be opened. What father among you, if his son asks for a fish, will give him a snake instead of a fish? read more.
Or if he asks for an egg, will give him a scorpion? If you, then, being evil [that is, sinful by nature], know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask and continue to ask Him!”

“Again I say to you, that if two believers on earth agree [that is, are of one mind, in harmony] about anything that they ask [within the will of God], it will be done for them by My Father in heaven. For where two or three are gathered in My name [meeting together as My followers], I am there among them.”

Jesus replied to them, “I assure you and most solemnly say to you, if you have faith [personal trust and confidence in Me] and do not doubt or allow yourself to be drawn in two directions, you will not only do what was done to the fig tree, but even if you say to this mountain, ‘Be taken up and thrown into the sea,’ it will happen [if God wills it]. And whatever you ask for in prayer, believing, you will receive.”

Jesus replied, “Have faith in God [constantly]. I assure you and most solemnly say to you, whoever says to this mountain, ‘Be lifted up and thrown into the sea!’ and does not doubt in his heart [in God’s unlimited power], but believes that what he says is going to take place, it will be done for him [in accordance with God’s will]. For this reason I am telling you, whatever things you ask for in prayer [in accordance with God’s will], believe [with confident trust] that you have received them, and they will be given to you.

And I will do whatever you ask in My name [as My representative], this I will do, so that the Father may be glorified and celebrated in the Son. If you ask Me anything in My name [as My representative], I will do it.

But of that [exact] day or hour no one knows, not even the angels in heaven, nor the Son [in His humanity], but the Father alone. “Be on guard and stay constantly alert [and pray]; for you do not know when the appointed time will come. It is like a man away on a journey, who when he left home put his servants in charge, each with his particular task, and also ordered the doorkeeper to be continually alert. read more.
Therefore, be continually on the alert—for you do not know when the master of the house is coming, whether in the evening, or at midnight, or when the rooster crows, or in the morning— [stay alert,] in case he should come suddenly and unexpectedly and find you asleep and unprepared. What I say to you I say to everyone, ‘Be on the alert [stay awake and be continually cautious]!’”

So when they had come together, they asked Him repeatedly, “Lord, are You at this time reestablishing the kingdom and restoring it to Israel?” He said to them, “It is not for you to know the times or epochs which the Father has fixed by His own authority.

Now as to the times and dates, brothers and sisters, you have no need for anything to be written to you. For you yourselves know perfectly well that the day of the [return of the] Lord is coming just as a thief [comes unexpectedly and suddenly] in the night.
