And we write this that our joy may be complete.

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

My little children, I write this to you so that you may not sin. But if anyone does sin, we have an advocate with the Father, Jesus Christ the righteous.

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

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

Little children, it is the last hour; and as you have heard that the Antichrist is coming, even now many antichrists have come; by this we know that it is the last 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.

And this is what he has promised useternal life.

And everyone who has this hope in him purifies himself, just as he is pure.

By this it may be seen who are the children of God, and who are the children of the devil: whoever does not do right is not of God, nor 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, that he laid down his life for us. And we also ought to lay down our lives for the brethren.

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 in the name of his Son Jesus Christ, and love one another, just as he has commanded us.

Now those who keep his commandments abide in him, and he in them. 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 has come in the flesh is of God,

and every spirit which does not confess Jesus is not of God. This is the spirit of the Antichrist, of which you have heard that it was coming, and now it is in the world already.

We are of God. Whoever 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.

In this the love of God was made manifest among us, that God sent his only 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 atoning sacrifice for our sins.

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

In this love is perfected among us, that we may have confidence for the Day of Judgment, because as he is so are we in this world.

And this commandment we have from him: that he who loves God must love his brother also.

By this we know that we love the children of God, when we love God and obey 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 worldour faith.

This is he who came by water and bloodJesus Christ; not only by water, but by water and blood.

If we receive the testimony of men, the testimony of God is greater; for this is the testimony of God which he has borne witness of his Son.

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

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

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