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

I write to you, little children, because your sins are forgiven you for his name's sake.

I have written to you, fathers, because you know him who is from the beginning. I have written to you, young men, because you are strong, and the word of God remains in you, and you have overcome the evil one.

Do not love the world, neither the things that are in the world. If anyone loves the world, the Father's love is not 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.

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.

Beloved, now we are children of God, and it is not yet revealed what we will be. We know that, when he is revealed, we will be like him; for we will see him just as he is.

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.

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

and whatever we ask, we receive from him, because we keep his commandments and do the things that are pleasing in his sight.

Beloved, do not believe every spirit, but test the spirits, whether they are of God, because many false prophets have gone out into the world.

You are of God, little children, and have overcome them; because greater is he who is in you than he who is in the world.

They are of the world. Therefore they speak of the world, and the world hears them.

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.

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.

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

For there are three who testify:

We know that we are of God, and the whole world lies in the power of the evil one.

We know that the Son of God has come, and has given us an understanding, that we know him who is true, and we are in him who is true, in his Son Jesus Christ. He is the true God and eternal life.
