Motivations for writing
12 Little children, I'm writing to you because your sins have been forgiven through Jesus' name.

Parents, I'm writing to you because you have known the one who has existed from the beginning. Young people, I'm writing to you because you have conquered the evil one.

Little children, I write to you because you know the Father. Parents, I write to you because you have known the one who has existed from the beginning. Young people, I write to you because you are strong, the word of God remains in you, and you have conquered the evil one.
Warning about the world
15 Don't love the world or the things in the world. If anyone loves the world, the love of the Father is not in them.
16
Everything that is in the world—the craving for whatever the body feels, the craving for whatever the eyes see and the arrogant pride in one's possessions—is not of the Father but is of the world.
17
And the world and its cravings are passing away, but the person who does the will of God remains forever.
