For when God made a promise to Abraham, since he could swear by no greater, he swore by himself, saying, "Surely blessing I will bless thee, and multiplying I will multiply thee."

Even as Abraham "believed God, and it was accounted to him as righteousness." Know then that they who have faith, these are the sons of Abraham. Moreover the Scripture, foreseeing that God was to accept the gentiles as righteous by faith, proclaimed beforehand the glad tidings to Abraham, saying, "In thee shall all nations be blessed." read more.
So then they who have faith are blessed with believing Abraham. For as many as rely on the works of the Law are under a curse; for it is written, "Cursed is every one that continueth not in all things which are written in the book of the Law, to do them." But further, that through the observance of the Law no one is accepted as righteous with God is evident; for "the righteous shall live by faith." And the Law hath nothing to do with faith; but [its language is], "He that hath done them shall live in them." Christ redeemed us from the curse of the Law, having become a curse for us; for it is written, "Cursed is every one that is hanged on a beam of wood," to the end that in Christ Jesus the blessing promised to Abraham might come to the gentiles, that we through faith might receive the Spirit which was promised. Brethren, I speak according to what is practised among men; no one sets aside even a human covenant, or makes additions to it, after it has been ratified. But the promises were made to Abraham and "to his offspring." He doth not say, "and to offsprings," as speaking of many, but, as speaking of one, "and to thy offspring," which is Christ. And what I mean is this; that a covenant that was before ratified by God, the Law, which came four hundred and thirty years after, cannot annul, so as to make void the promise; for if the inheritance cometh from the Law, it ceaseth to be the consequence of the promise; but to Abraham God gave it by promise.


For it is written, that Abraham had two sons; the one by the bondwoman, the other by the freewoman. But the one by the bondwoman was born after the flesh; while the one by the freewoman was through the promise. Which things are written allegorically; for these women are two covenants; the one from Mount Sinai, who beareth children into bondage, which is Hagar; read more.
for the word Hagar is Mount Sinai in Arabia; and she corresponds to the Jerusalem now existing, for she is in bondage with her children; but the Jerusalem that is above is free, and she is our mother. For it is written: "Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not; for many are the children of the desolate one, rather than of her who hath the husband." But ye, brethren, as Isaac was, are children of a promise. But as at that time he that was born after the flesh persecuted him that was born through the Spirit, so it is now. But what saith the scripture? "Cast out the bondwoman and her son; for the son of the bondwoman shall not be heir with the son of the freewoman." So then, brethren, we are not children of a bondwoman, but of the freewoman.


What advantage then shall we say that Abraham our father had as to the flesh? For if Abraham was accepted as righteous through works, he hath ground of boasting. But he hath no ground of boasting before God. For what saith the scripture? "Abraham had faith in God, and it was accounted unto him as righteousness." read more.
Now to him that performeth works, the reward is not accounted a matter of grace, but of debt; but to him who without performing works hath faith in him who accepteth as righteous one that hath been ungodly, his faith is accounted as righteousness; as David also speaketh of the blessedness of the man whom God accepteth as righteous without works: "Blessed are they whose iniquities are forgiven, and whose sins are covered. Blessed is the man whom the Lord shall not charge with sin." Doth this blessedness belong to the circumcised alone, or to the uncircumcised also? For we are saying that Abrahams faith was accounted as righteousness. How then was it so accounted? After his circumcision, or while he was uncircumcised? Not after he was circumcised, but while he was uncircumcised. And he received the outward sign of circumcision as a seal of the righteousness of the faith which he had while he was uncircumcised; that he might be the father of all the uncircumcised who have faith, so that righteousness might be put to their account also; and that he might be the father of the circumcised, who are not circumcised merely, but who tread in the steps of that faith which our father Abraham had while yet uncircumcised. For not through the Law was the promise made to Abraham or his offspring that he should be the heir of the world, but through the righteousness of faith. For if they that are of the Law are heirs, then faith becometh a vain thing, and the promise is made of no effect. For the Law is the cause of wrath; for where there is no law there is no transgression. Therefore the inheritance was made to depend on faith, that it might be a matter of grace; that the promise might be sure to all the offspring, not to that only which is under the Law, but to that also which hath the faith of Abraham, who is the father of us all (as it is written, "I have made thee a father of many nations") in the sight of that God whom he believed, who giveth life to the dead, and calleth the things that are not, as though they were. For he had confident hope in that which was past hope, that he should become a father of many nations, according to that which was spoken, "Thus shall thy offspring be;" and not being weak in faith, he regarded not his own body which had become dead, he being about a hundred years old, nor the deadness of Sarahs womb; nor did he waver in respect to the promise of God through unbelief, but was strong in faith, giving glory to God; being fully convinced, that what he hath promised, he is able also to perform. And therefore it was accounted to him for righteousness.

Even as Abraham "believed God, and it was accounted to him as righteousness." Know then that they who have faith, these are the sons of Abraham. Moreover the Scripture, foreseeing that God was to accept the gentiles as righteous by faith, proclaimed beforehand the glad tidings to Abraham, saying, "In thee shall all nations be blessed." read more.
So then they who have faith are blessed with believing Abraham.

By faith Abraham, when called, obeyed to go forth to a place which he was afterward to receive for an inheritance, and went forth, not knowing whither he was going. By faith he sojourned in the land of the promise, as in a foreign country, dwelling in tents with Isaac and Jacob, the heirs with him of the same promise; for he was looking for the city which hath foundations, whose maker and builder is God.

By faith Abraham, when tried, offered up Isaac, and he who had received the promises was offering up his onlybegotten son, he to whom it was said, "From Isaac shall thine offspring be reckoned;" accounting that God is able even to raise from the dead; whence also he did figuratively receive him back.

Was not Abraham our father accepted as righteous through works, when he offered Isaac his son upon the altar? Thou seest that faith wrought with his works, and by works was faith made perfect. And the scripture was fulfilled, which saith, "Abraham believed God, and it was reckoned to him for righteousness;" and he was called the friend of God. read more.
Ye see that by works a man is accounted as righteous, and not by faith only.

And as he held fast to Peter and John, all the people ran together to them in the porch that is called Solomons greatly wondering. But Peter seeing it, answered the people: Men of Israel, why wonder ye at this? Or why look ye earnestly on us, as though by our own power or godliness we had made this man to walk? The God of Abraham and Isaac and Jacob, the God of our fathers, hath glorified his servant Jesus, whom ye indeed delivered up, and denied him in the presence of Pilate, when he had decided to release him. read more.
But ye denied the holy and righteous one, and asked that a murderer should be granted to you. But the author of life ye killed; whom God raised from the dead, whereof we are witnesses. And his name, through faith in his name, made this man strong, whom ye see and know; yea, the faith which is through him gave him this perfect soundness in the presence of you all.

We conclude therefore, that a man is accepted as righteous through faith, without the works of the Law. Or is God [the God] of Jews alone? Is he not also the God of gentiles? Yea, of gentiles also. Seeing there is but one God, who will accept the circumcised as righteous by faith, and the uncircumcised through faith. read more.
Do we then make void the Law through faith? Far be it! On the contrary, we establish the Law.

For by grace ye have been saved, through faith; and this is not of yourselves; it is the gift of God; not of works, lest any one should boast. For we are his workmanship, created in Christ Jesus unto good works, which God before prepared that we should walk in them.

Now faith is assurance of things hoped for, a conviction of things not seen. For by it the elders obtained a good report. Through faith we perceive that the worlds were framed by the word of God, so that that which is seen hath not been made out of things which appear. read more.
By faith Abel offered to God a more excellent sacrifice than Cain, through which he received testimony that he was righteous, God testifying of his gifts; and by it though dead he yet speaketh. By faith Enoch was translated, that he should not see death; and he was not found, because God translated him; for before his translation he had the testimony that he pleased God. But without faith it is impossible to please him; for he that cometh to God must believe that he is, and that he is a rewarder of those who diligently seek him. By faith Noah, being warned by God of things not yet seen, moved with fear, prepared an ark for the saving of his house; by which he condemned the world, and became heir of the righteousness which is according to faith. By faith Abraham, when called, obeyed to go forth to a place which he was afterward to receive for an inheritance, and went forth, not knowing whither he was going. By faith he sojourned in the land of the promise, as in a foreign country, dwelling in tents with Isaac and Jacob, the heirs with him of the same promise; for he was looking for the city which hath foundations, whose maker and builder is God. Through faith Sarah herself also received power to conceive, even when she was past age, because she accounted him faithful who had promised.

So then they who have faith are blessed with believing Abraham. Verse ConceptsFaithfulness, Examples OfThose Who Had FaithHaving FaithBlessings From Godbelief

And the apostles and the elders came together to consider this matter. And after much debate, Peter rose up and said to them, Brethren, ye know that a long time ago God made choice among you, that by my mouth the gentiles should hear the word of the glad tidings, and believe. And God, who knoweth the heart, bore them witness, giving them the Holy Spirit, as he gave it to us; read more.
and made no difference between us and them, having purified their hearts by faith. Now therefore why do ye provoke the anger of God, by putting a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear? But we believe that we shall be saved through the grace of the Lord Jesus, in the same manner as they.

So, disagreeing with one another, they took their departure, after Paul had spoken one word: Well did the Holy Spirit speak through Isaiah the prophet to your fathers, saying, "Go to this people, and say, Hearing ye shall hear, and shall not understand; and seeing ye shall see and not perceive. For the heart of this people hath become gross, and their ears are dull of hearing, and their eyes they have closed; lest they should see with their eyes and hear with their ears, and understand with their heart and turn from their ways, and I should heal them." read more.
Be it therefore known to you, that to the gentiles this salvation of God hath been sent; they, moreover, will hear.

What then shall we say? That the gentiles, who did not strive after righteousness, obtained righteousness, but a righteousness which is of faith; while Israel, which strove after a law of righteousness, did not attain to a law of righteousness. Why? Because they did not strive for it by faith, but as being by works. For they stumbled against the stone of stumbling; read more.
as it is written, "Behold, I lay in Zion a stone of stumbling and rock of offence; and he that believeth in him shall not be put to shame."

I say then, Hath God cast off his people? Far be it I For I myself am an Israelite, of the seed of Abraham, of the tribe of Benjamin. God hath not cast off his people, which he foreknew. Do ye not know what the Scripture saith in the passage concerning Elijah? how he pleadeth to God against Israel: "Lord, they have killed thy prophets, they have dug down thine altars; and I am left alone, and they are seeking my life." read more.
But what saith the answer of God to him? "I have reserved to myself seven thousand men, who have not bowed the knee to Baal." In the same way then at this present time also there is a remnant, according to the election of grace. And if it is by grace, it is no longer on account of works; otherwise grace ceaseth to be grace; but if it is of works, there is then no grace; otherwise work ceaseth to be work. How is it then? What Israel seeketh after, that Israel did not obtain; but the elect obtained it, and the rest were hardened; as it is written: "God gave them a spirit of slumber, eyes that were not to see, and ears that were not to hear, unto this day." And David saith, "Let their table become a snare, and a trap, and a stumblingblock, and a recompense to them; let their eyes be darkened, that they may not see; and bow down their back alway." I say then, Did they stumble in order to fall? God forbid! But by their offence salvation is come to the gentiles to excite them to emulation. But if their offence is the riches of the world, and their loss the riches of the gentiles, how much more will their fullness be? For I am speaking to you gentiles; inasmuch as I am the apostle of the gentiles, I magnify my office, that I may, if possible, excite to emulation those who are my flesh, and may save some of them. For if the rejection of them is the reconciliation of the world, what will the reception of them be, but life from the dead? And if the first portion of the dough is holy, so also will be the lump; and if the root is holy, so will be the branches. And if some of the branches have been broken off, and thou, a wild olive, hast been grafted in among them, and become a partaker with them of the root and fatness of the olivetree, boast not over the branches; for if thou boast, thou dost not bear the root, but the root thee. Thou wilt say then, The branches were broken off, that I might be grafted in. Be it so. It was for their unbelief that they were broken off, and thou standest through thy faith; be not highminded, but fear. For if God spared the natural branches, take care lest he spare not thee. Behold then the goodness and the severity of God; toward those who fell, severity; but toward thee Gods goodness, if thou continue in his goodness; otherwise thou also wilt be cut off. And they also, if they do not continue in their unbelief, will be grafted in; for God is able to graft them in again. For if thou hast been cut off from an olivetree wild by nature, and hast against thy nature been ingrafted into a good olivetree, how much more shall these, the natural branches, be ingrafted into their own olivestock? For I would not have you ignorant, brethren, of this mystery, lest ye should be wise in your own conceits, that blindness hath to some extent come upon Israel, until the fullness of the gentiles shall have come in. And thus will all Israel be saved; as it is written, "There shall come out of Zion the Deliverer; he shall turn away ungodliness from Jacob. And this will be my covenant with them, when I shall have taken away their sins." In regard to the gospel, they are enemies for your sakes; but in regard to Gods choice, they are beloved for the fathers sake. For in respect to his gifts and his calling, there is no change of purpose with God. For as ye in times past were disobedient to God, but have now obtained mercy through their disobedience, so they too have now become disobedient, that they also may obtain mercy through the mercy shown to you. For God delivered up all to disobedience, that he might have mercy upon all.

And in like manner was not also Rahab the harlot accounted as righteous through works, when she received the messengers, and sent them out another way?


There is then now no condemnation for those who are in Christ Jesus. For the law of the Spirit of life set me free in Christ Jesus from the law of sin and death. For what the Law could not do, in that it was weak through the flesh, God hath done, who on account of sin sent his own Son in the likeness of sinful flesh, and passed sentence of condemnation on sin in the flesh; read more.
so that what is required by the Law might be accomplished in us, who walk not according to the flesh, but according to the Spirit.



God hath fulfilled to us their children, in raising up Jesus [from the dead]; as it is also written in the first Psalm: "Thou art my Son; I have this day begotten thee." And that he raised him up from the dead, no more to return to corruption, he hath thus spoken: "I will give you the sure holy things promised to David." Wherefore also in another Psalm he saith, "Thou wilt not suffer thy holy one to see corruption:" read more.
For David, after having in his own generation served the will of God, fell asleep, and was added to his fathers, and saw corruption; but he whom God raised from the dead did not see corruption.

For the Law but shadowing forth the good things to come, and not having the very image of the things, can never with the same sacrifices which they offer year by year continually make those who come with them perfect. For in that case would they not have ceased to be offered, because the worshippers, having been once purified, would have had no more consciousness of sins? But in these sacrifices there is a remembrance of sins every year. read more.
For it is impossible that the blood of bulls and goats should take away sins. Wherefore, when he cometh into the world, he saith: "Sacrifice and offering thou wouldest not, but a body didst thou prepare for me; in whole burntofferings and sacrifices for sin thou hadst no pleasure. Then said I, Lo, I have comein the volume of the book it is written of meto do thy will, O God." Saying above, "Sacrifices and offerings, and whole burntofferings and sacrifices for sin thou wouldest not, and hadst no pleasure in them,"such as are offered in conformity to the Law, then hath he said, "Lo, I have come to do thy will." He setteth aside the first, that he may establish the second. And in this will we have been sanctified through the offering of the body of Jesus Christ once for all. And every priest indeed standeth performing daily service, and offering again and again the same sacrifices, which can never take away sins; but he, after he had offered one sacrifice for sins, sat down for ever on the right hand of God, thenceforth waiting until his enemies be made his footstool. For by one offering he hath perfected for ever those who are sanctified. Moreover the Holy Spirit also is a witness to us of this. For after he had said,
