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

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

I have written unto you, fathers, because you have known him who is from the beginning. I have written unto you, young men, because you are strong, and the word of God abides in you, and you have overcome the wicked one.

Love not the world, neither the things that are in the world. If any man loves the world, the love of the Father is not in him.

Little children, it is the last time: and as you have heard that antichrist shall come, even now are there many antichrists; by which we know that it is the last time.

Beloved, now are we the children of God, and it does not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.

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.

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

And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.

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

You are of God, little children, and have overcome them: because greater is he that is in you, than he that 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 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 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.

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

For there are three that bear witness in heaven, the Father, the Word, and the Holy Spirit: and these three are one.

And there are three that bear witness in earth, the Spirit, and the water, and the blood: and these three agree in one.

And we know that we are of God, and the whole world lies in wickedness.

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.
