3 What marvelous love the Father has extended to us! Just look at it—we’re called children of God! That’s who we really are. But that’s also why the world doesn’t recognize us or take us seriously, because it has no idea who he is or what he’s up to.

^2-3 But friends, that’s exactly who we are: children of God. And that’s only the beginning. Who knows how we’ll end up! What we know is that when Christ is openly revealed, we’ll see him—and in seeing him, become like him. All of us who look forward to his Coming stay ready, with the glistening purity of Jesus’ life as a model for our own.

^4-6 All who indulge in a sinful life are dangerously lawless, for sin is a major disruption of God’s order. Surely you know that Christ showed up in order to get rid of sin. There is no sin in him, and sin is not part of his program. No one who lives deeply in Christ makes a practice of sin. None of those who do practice sin have taken a good look at Christ. They’ve got him all backward.

^7-8 So, my dear children, don’t let anyone divert you from the truth. It’s the person who acts right who is right, just as we see it lived out in our righteous Messiah. Those who make a practice of sin are straight from the Devil, the pioneer in the practice of sin. The Son of God entered the scene to abolish the Devil’s ways.

^9-10 People conceived and brought into life by God don’t make a practice of sin. How could they? God’s seed is deep within them, making them who they are. It’s not in the nature of the God-born to practice and parade sin. Here’s how you tell the difference between God’s children and the Devil’s children: The one who won’t practice righteous ways isn’t from God, nor is the one who won’t love brother or sister. A simple test.

¹¹ For this is the original message we heard: We should love each other.

^12-13 We must not be like Cain, who joined the Evil One and then killed his brother. And why did he kill him? Because he was deep in the practice of evil, while the acts of his brother were righteous. So don’t be surprised, friends, when the world hates you. This has been going on a long time.

^14-15 The way we know we’ve been transferred from death to life is that we love our brothers and sisters. Anyone who doesn’t love is as good as dead. Anyone who hates a brother or sister is a murderer, and you know very well that eternal life and murder don’t go together.

^16-17 This is how we’ve come to understand and experience love: Christ sacrificed his life for us. This is why we ought to live sacrificially for our fellow believers, and not just be out for ourselves. If you see some brother or sister in need and have the means to do something about it but turn a cold shoulder and do nothing, what happens to God’s love? It disappears. And you made it disappear.

When We Practice Real Love

^18-20 My dear children, let’s not just talk about love; let’s practice real love. This is the only way we’ll know we’re living truly, living in God’s reality. It’s also the way to shut down debilitating self-criticism, even when there is something to it. For God is greater than our worried hearts and knows more about us than we do ourselves.

^21-24 And friends, once that’s taken care of and we’re no longer accusing or condemning ourselves, we’re bold and free before God! We’re able to stretch our hands out and receive what we asked for because we’re doing what he said, doing what pleases him. Again, this is God’s command: to believe in his personally named Son, Jesus Christ. He told us to love each other, in line with the original command. As we keep his commands, we live deeply and surely in him, and he lives in us. And this is how we experience his deep and abiding presence in us: by the Spirit he gave us.

Don’t Believe Everything You Hear

4 My dear friends, don’t believe everything you hear. Carefully weigh and examine what people tell you. Not everyone who talks about God comes from God. There are a lot of lying preachers loose in the world.

^2-3 Here’s how you test for the genuine Spirit of God. Everyone who confesses openly his faith in Jesus Christ—the Son of God, who came as an actual flesh-and-blood person—comes from God and belongs to God. And everyone who refuses to confess faith in Jesus has nothing in common with God. This is the spirit of antichrist that you heard was coming. Well, here it is, sooner than we thought!

^4-6 My dear children, you come from God and belong to God. You have already won a big victory over those false teachers, for the Spirit in you is far stronger than anything in the world. These people belong to the Christ-denying world. They talk the world’s language and the world eats it up. But we come from God and belong to God. Anyone who knows God understands us and listens. The person who has nothing to do with God will, of course, not listen to us. This is another test for telling the Spirit of Truth from the spirit of deception.

God Is Love

^7-10 My beloved friends, let us continue to love each other since love comes from God. Everyone who loves is born of God and experiences a relationship with God. The person who refuses to love doesn’t know the first thing about God, because God is love—so you can’t know him if you don’t love. This is how God showed his love for us: God sent his only Son into the world so we might live through him. This is the kind of love we are talking about—not that we once upon a time loved God, but that he loved us and sent his Son as a sacrifice to clear away our sins and the damage they’ve done to our relationship with God.

^11-12 My dear, dear friends, if God loved us like this, we certainly ought to love each other. No one has seen God, ever. But if we love one another, God dwells deeply within us, and his love becomes complete in us—perfect love!

^13-16 This is how we know we’re living steadily and deeply in him, and he in us: He’s given us life from his life, from his very own Spirit. Also, we’ve seen for ourselves and continue to state openly that the Father sent his Son as Savior of the world. Everyone who confesses that Jesus is God’s Son participates continuously in an intimate relationship with God. We know it so well, we’ve embraced it heart and soul, this love that comes from God.

To Love, to Be Loved

^17-18 God is love. When we take up permanent residence in a life of love, we live in God and God lives in us. This way, love has the run of the house, becomes at home and mature in us, so that we’re free of worry on Judgment Day—our standing in the world is identical with Christ’s. There is no room in love for fear. Well-formed love banishes fear. Since fear is crippling, a fearful life—fear of death, fear of judgment—is one not yet fully formed in love.

¹⁹ We, though, are going to love—love and be loved. First we were loved, now we love. He loved us first.

^20-21 If anyone boasts, “I love God,” and goes right on hating his brother or sister, thinking nothing of it, he is a liar. If he won’t love the person he can see, how can he love the God he can’t see? The command we have from Christ is blunt: Loving God includes loving people. You’ve got to love both.
