7 But if we live in the light in the same way that God is in the light, we have a relationship with each other. And the blood of his Son Jesus cleanses us from every sin. 8 If we say, “We aren’t sinful” we are deceiving ourselves, and the truth is not in us. 9 God is faithful and reliable. If we confess our sins, he forgives them and cleanses us from everything we’ve done wrong. 10 If we say, “We have never sinned,” we turn God into a liar and his Word is not in us.
1 My dear children, I’m writing this to you so that you will not sin. Yet, if anyone does sin, we have Jesus Christ, who has God’s full approval. He speaks on our behalf when we come into the presence of the Father. 2 He is the payment for our sins, and not only for our sins, but also for the sins of the whole world.
3 We are sure that we know Christ if we obey his commandments. 4 The person who says, “I know him,” but doesn’t obey his commandments is a liar. The truth isn’t in that person. 5 But whoever obeys what Christ says is the kind of person in whom God’s love is perfected. That’s how we know we are in Christ. 6 Those who say that they live in him must live the same way he lived.
7 Dear friends, it’s not as though I’m writing to give you a new commandment. Rather, I’m giving you an old commandment that you’ve had from the beginning. It’s the old commandment you’ve already heard. 8 On the other hand, I’m writing to give you a new commandment. It’s a truth that exists in Christ and in you: The darkness is fading, and the true light is already shining.
9 Those who say that they are in the light but hate other believers are still in the dark. 10 Those who love other believers live in the light. Nothing will destroy the faith of those who live in the light. 11 Those who hate other believers are in the dark and live in the dark. They don’t know where they’re going, because they can’t see in the dark.
