And we write this that our joy may be complete.

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.

They went out from us, but they were not of us; for if they had been of us, they would have continued with us; but they went out that it might be plain that none of them were of us.

And now, little children, abide in him, so that when he appears we may have confidence and not be ashamed before him at his coming.

See what love the Father has given us, that we should be called children of God! And so we are! The reason why the world does not know us is that it did not know him.

Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when he appears, we shall be like him, for we shall see him as he is.

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.

and not be like Cain who was of the evil one and murdered his brother. And why did he murder him? Because his own deeds were evil and his brother's righteous.

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

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,

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 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.

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

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