And this is the message which we have heard from Him and declare to you, that God is light, and in Him is no darkness at all.

And by this we know that we have known Him, if we keep His commandments.

But whoever keeps His Word, truly in this one the love of God is perfected. By this we know that we are in Him.

And this is the promise that He has promised us: everlasting life.

And everyone who has this hope on him purifies himself, even as that One is pure.

He who practices sin is of the Devil, for the Devil sins from the beginning. For this purpose the Son of God was revealed, that He might undo the works of the Devil.

In this the children of God are revealed, and the children of the Devil: everyone not practicing righteousness is not of God, also he who does not love his brother.

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

By this we have known the love of God, because He laid down His life for us. And we ought to lay down our lives for the brothers.

But whoever has this world's goods and sees his brother having need, and shuts up his bowels from him, how does the love of God dwell in him?

And in this we shall 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 who keeps His commandment dwells in Him, and He in him. And by this we know that He abides in us, by the Spirit which He gave to us.

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

and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the antichrist you heard is coming, and even now is already in the world.

We are of God. He who knows God hears us. The one who is not of God does not hear us. From this we know the spirit of truth and the spirit of error.

In this the love of God was revealed in 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 concerning 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, that as He is, so also we are in this world.

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

By this we know that we love the children of God, whenever 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 everything that has been born of God overcomes the world. And this is the victory that overcomes the world, our faith.

This is He who came through water and blood, Jesus Christ, not by water only, but by the water and blood. And the Spirit is He who bears witness, because the Spirit is the 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 about His Son.

And this is the record, that God has given to us everlasting life, and this life is in His Son.

And this is the confidence that we have toward Him, that if we ask anything according to His will, He hears us.

And we know that the Son of God has come, and He has given us an understanding so that we may know Him who is true. And we are in Him that is true, in His Son Jesus Christ. This is the true God, and the everlasting life.
