The life appeared; we have seen it and testify to it, and we proclaim to you the eternal life, which was with the Father and has appeared to us.

We proclaim to you what we have seen and heard, so that you also may have fellowship with us. And our fellowship is with the Father and with his Son, Jesus Christ.

My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One.

I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men, because you have overcome the evil one.

I write to you, dear children, because you know the Father. I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you are strong, and the word of God lives in you, and you have overcome the evil one.

On Not Loving the World

Do not love the world or anything in the world. If anyone loves the world, love for the Father is not in them.

For everything in the world—the lust of the flesh, the lust of the eyes, and the pride of life—comes not from the Father but from the world.

Who is the liar? It is whoever denies that Jesus is the Christ. Such a person is the antichrist—denying the Father and the Son.

No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.

As for you, see that what you have heard from the beginning remains in you. If it does, you also will remain in the Son and in the Father.

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

And we have seen and testify that the Father has sent his Son to be the Savior of the world.

Faith in the Incarnate Son of God

Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the father loves his child as well.
