This is the message which we have heard from him and announce to you, that God is light, and in him is no darkness at all.

This is how we know that we know him: if we keep his commandments.

But whoever keeps his word, God's love has truly been perfected in him. This is how we know that we are in him:

Little children, these are the end times, and as you heard that the antichrist is coming, even now many antichrists have arisen. By this we know that it is the final hour.

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

This is the promise which he promised us, the eternal life.

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

Everyone who has this hope set on him purifies himself, even as he is pure.

He who sins is of the devil, for the devil has been sinning from the beginning. To this end the Son of God was revealed, to destroy the works of the devil.

In this the children of God are revealed, and the children of the devil. Whoever does not do righteousness is not of God, neither is he who does not love his brother.

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

By this we know love, because he laid down his life for us. And we ought to lay down our lives for the brothers.

And by this we will know that we are of the truth, and persuade our heart before him,

This is his commandment, that we should believe in the name of his Son, Jesus Christ, and love one another, even as he commanded us.

He who keeps his commandments remains in him, and he in him. By this we know that he remains in us, by the Spirit which he gave us.

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

and every spirit who does not confess Jesus is not of God; and this is that of the antichrist, of whom you have heard that it comes. Now it is in the world already.

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

By this God's love was revealed in us, that God has sent his one and only Son into the world that we might live through him.

In this is love, not that we have loved God, but that he loved us, and sent his Son as the atoning sacrifice for our sins.

Beloved, if God loved us in this way, we also ought to love one another.

By this we know that we remain in him and he in us, because he has given us of his Spirit.

In this love has been made perfect among us, that we may have boldness in the day of judgment, because as he is, even so are we in this world.

This commandment we have from him, that he who loves God should also love his brother.

By this we know that we love the children of God, when we love God and do his commandments.

For this is the love of God, that we keep his commandments. His commandments are not grievous.

For whatever is born of God overcomes the world. This is the victory that has overcome the world: our faith.

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

If we receive the witness of men, the witness of God is greater; for this is God's testimony that he has testified concerning his Son.

The testimony is this, that God gave to us eternal life, and this life is in his Son.

This is the boldness which we have toward him, that, if we ask anything according to his will, he listens to us.

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