This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.

And by this we know that we know him, if we keep his commandments.

But whoever keeps his word, in him verily is the love of God perfected: by this we know that we are in him.

And this is the promise that he has promised us, even eternal life.

And every man that has this hope in him purifies himself, even as he is pure.

He that commits sin is of the devil; for the devil sins from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.

In this the children of God are manifest, and the children of the devil: whosoever does not righteousness is not of God, neither he that loves not his brother.

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

By this perceive we the love of God, because he laid down his life for us: and we ought to lay down our lives for the brethren.

But whoever has this world's goods, and sees his brother have need, and shuts up his heart of compassion from him, how dwells the love of God in him?

And by this we know that we are of the truth, and shall assure our hearts before him.

And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.

And he that keeps his commandments dwells in him, and he in him. And by this we know 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 is come in the flesh is of God:

And every spirit that confesses not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, of which you have heard that it should come; and even now already is it in the world.

We are of God: he that knows God hears us; he that is not of God hears not us. By this we know the spirit of truth, and the spirit of error.

In this was manifested the love of God toward us, because God sent his only begotten Son into the world, 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 dwell in him, and he in us, because he has given us of his Spirit.

In this is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.

And this commandment have we from him, That he who loves God love his brother also.

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

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

For whoever is born of God overcomes the world: and this is the victory that overcomes the world, even our faith.

This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that bears witness, because the Spirit is truth.

If we receive the witness of men, the witness of God is greater: for this is the witness of God which he has testified of his Son.

And this is the witness, that God has given to us eternal life, and this life is in his Son.

And this is the confidence that we have in him, that, if we ask anything according to his will, he hears us:

And we know that the Son of God is come, and has given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.
