what we have seen and heard we also proclaim to you, so that you too may have fellowship [as partners] with us. And indeed our fellowship [which is a distinguishing mark of born-again believers] is with the Father, and with His Son Jesus Christ.

This is the message [of God’s promised revelation] which we have heard from Him and now announce to you, that God is Light [He is holy, His message is truthful, He is perfect in righteousness], and in Him there is no darkness at all [no sin, no wickedness, no imperfection].

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).

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:

Children, it is the last hour [the end of this age]; and just as you heard that the antichrist is coming [the one who will oppose Christ and attempt to replace Him], even now many antichrists (false teachers) have appeared, which confirms our belief that it is the last hour.

This is the promise which He Himself promised us—eternal life.

These things I have written to you with reference to those who are trying to deceive you [seducing you and leading you away from the truth and sound doctrine].

And everyone who has this hope [confidently placed] in Him purifies himself, just as He is pure (holy, undefiled, guiltless).

By this the children of God and the children of the devil are clearly identified: anyone who does not practice righteousness [who does not seek God’s will in thought, action, and purpose] is not of God, nor is the one who does not [unselfishly] love his [believing] brother.

For this is the message which you [believers] have heard from the beginning [of your relationship with Christ], that we should [unselfishly] love and seek the best for one another;

By this we know [and have come to understand the depth and essence of His precious] love: that He [willingly] laid down His life for us [because He loved us]. And we ought to lay down our lives for the believers.

But whoever has the world’s goods (adequate resources), and sees his brother in need, but has no compassion for him, how does the love of God live in him?

By this we will know [without any doubt] that we are of the truth, and will assure our heart and quiet our conscience before Him

This is His commandment, that we believe [with personal faith and confident trust] in the name of His Son Jesus Christ, and [that we unselfishly] love and seek the best for one another, just as He commanded us.

The one who habitually keeps His commandments [obeying His word and following His precepts, abides and] remains in Him, and He in him. By this we know and have the proof that He [really] abides in us, by the Spirit whom He has given us [as a gift].

By this you know and recognize the Spirit of God: every spirit that acknowledges and confesses [the fact] that Jesus Christ has [actually] come in the flesh [as a man] is from God [God is its source];

and every spirit that does not confess Jesus [acknowledging that He has come in the flesh, but would deny any of the Son’s true nature] is not of God; this is the spirit of the antichrist, which you have heard is coming, and is now already in the world.

We [who teach God’s word] are from God [energized by the Holy Spirit], and whoever knows God [through personal experience] listens to us [and has a deeper understanding of Him]. Whoever is not of God does not listen to us. By this we know [without any doubt] the spirit of truth [motivated by God] and the spirit of error [motivated by Satan].

By this the love of God was displayed in us, in that God has sent His [One and] only begotten Son [the One who is truly unique, the only One of His kind] into the world so that we might live through Him.

In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation [that is, the atoning sacrifice, and the satisfying offering] for our sins [fulfilling God’s requirement for justice against sin and placating His wrath].

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.

In this [union and fellowship with Him], love is completed and perfected with us, so that we may have confidence in the day of judgment [with assurance and boldness to face Him]; because as He is, so are we in this world.

And this commandment we have from Him, that the one who loves God should also [unselfishly] love his brother and seek the best for him.

By this we know [without any doubt] that we love the children of God: [expressing that love] when we love God and obey His commandments.

For the [true] love of God is this: that we habitually keep His commandments and remain focused on His precepts. And His commandments and His precepts are not difficult [to obey].

For everyone born of God is victorious and overcomes the world; and this is the victory that has conquered and overcome the world—our [continuing, persistent] faith [in Jesus the Son of God].

This is He who came through water and blood [His baptism and death], Jesus Christ—not by the water only, but by the water and the blood. It is the [Holy] Spirit who testifies, because the Spirit is the truth. [He is the essence and origin of truth itself.]

If we accept [as we do] the testimony of men [that is, if we are willing to take the sworn statements of fallible humans as evidence], the testimony of God is greater [far more authoritative]; for this is the testimony of God, that He has testified regarding His Son.

The one who believes in the Son of God [who adheres to, trusts in, and relies confidently on Him as Savior] has the testimony within himself [because he can speak authoritatively about Christ from his own personal experience]. The one who does not believe God [in this way] has made Him [out to be] a liar, because he has not believed in the evidence that God has given regarding His Son.

And the testimony is this: God has given us eternal life [we already possess it], and this life is in His Son [resulting in our spiritual completeness, and eternal companionship with Him].

These things I have written to you who believe in the name of the Son of God [which represents all that Jesus Christ is and does], so that you will know [with settled and absolute knowledge] that you [already] have eternal life.

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 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.
