This is the message we have heard from Him and announce to you, that God is Light, and in Him there is no darkness at all.

By this we know that we have come to know Him, if we keep His commandments.

but whoever keeps His word, in him the love of God has truly been perfected. By this we know that we are in Him:

Children, it is the last hour; and just as you heard that antichrist is coming, even now many antichrists have appeared; from this we know that it is the last hour.

Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son.

This is the promise which He Himself made to us: eternal life.

See how great a love the Father has bestowed on us, that we would be called children of God; and such we are. For this reason the world does not know us, because it did not know Him.

And everyone who has this hope fixed on Him purifies himself, just as He is pure.

the one who practices sin is of the devil; for the devil has sinned from the beginning. The Son of God appeared for this purpose, to destroy the works of the devil.

By this the children of God and the children of the devil are obvious: anyone who does not practice righteousness is not of God, nor the one who does not love his brother.

For this is the message which you have heard from the beginning, that we should love one another;

We know love by this, that He laid down His life for us; and we ought to lay down our lives for the brethren.

We will know by this that we are of the truth, and will assure our heart before Him

This is His commandment, that we believe in the name of His Son Jesus Christ, and love one another, just as He commanded us.

The one who keeps His commandments abides in Him, and He in him. We know by this that He abides in us, by the Spirit whom He has given us.

By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God;

and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world.

We are from God; he who knows God listens to us; he who is not from God does not listen to us. By this we know the spirit of truth and the spirit of error.

By this the love of God was manifested in us, that God has sent His only begotten Son 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 for our sins.

By this we know that we abide in Him and He in us, because He has given us of His Spirit.

By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world.

And this commandment we have from Him, that the one who loves God should love his brother also.

By this we know that we love the children of God, when we love God and observe His commandments.

For this is the love of God, that we keep His commandments; and His commandments are not burdensome.

For whatever is born of God overcomes the world; and this is the victory that has overcome the world—our faith.

This is the One who came by water and blood, Jesus Christ; not with the water only, but with the water and with the blood. It is the Spirit who testifies, because the Spirit is the truth.

If we receive the testimony of men, the testimony of God is greater; for the testimony of God is this, that He has testified concerning His Son.

And the testimony is this, that God has given us eternal life, and this life is in His Son.

This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us.

If anyone sees his brother committing a sin not leading to death, he shall ask and God will for him give life to those who commit sin not leading to death. There is a sin leading to death; I do not say that he should make request for this.

And we know that the Son of God has come, and has given us understanding so that we may 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.
