I write this, dear children, to guide you out of sin. But if anyone does sin, we have a Priest-Friend in the presence of the Father: Jesus Christ, righteous Jesus. When he served as a sacrifice for our sins, he solved the sin problem for good—not only ours, but the whole world's.
The Only Way to Know We're in Him2-3Here's how we can be sure that we know God in the right way: Keep his commandments.
4-6If someone claims, "I know him well!" but doesn't keep his commandments, he's obviously a liar. His life doesn't match his words. But the one who keeps God's word is the person in whom we see God's mature love. This is the only way to be sure we're in God. Anyone who claims to be intimate with God ought to live the same kind of life Jesus lived.
7-8My dear friends, I'm not writing anything new here. This is the oldest commandment in the book, and you've known it from day one. It's always been implicit in the Message you've heard. On the other hand, perhaps it is new, freshly minted as it is in both Christ and you—the darkness on its way out and the True Light already blazing!
9-11Anyone who claims to live in God's light and hates a brother or sister is still in the dark. It's the person who loves brother and sister who dwells in God's light and doesn't block the light from others. But whoever hates is still in the dark, stumbles around in the dark, doesn't know which end is up, blinded by the darkness.
Loving the World12-13I remind you, my dear children: Your sins are forgiven in Jesus' name. You veterans were in on the ground floor, and know the One who started all this; you newcomers have won a big victory over the Evil One.
13-14And a second reminder, dear children: You know the Father from personal experience. You veterans know the One who started it all; and you newcomers—such vitality and strength! God's word is so steady in you. Your fellowship with God enables you to gain a victory over the Evil One.
15-17Don't love the world's ways. Don't love the world's goods. Love of the world squeezes out love for the Father. Practically everything that goes on in the world—wanting your own way, wanting everything for yourself, wanting to appear important—has nothing to do with the Father. It just isolates you from him. The world and all its wanting, wanting, wanting is on the way out—but whoever does what God wants is set for eternity.
