But whoever continually keeps his commandments is the kind of person in whom God's love has truly been perfected. This is how we can be sure that we are in union with God:

Dear friends, I am not writing to you a new commandment, but an old commandment that you have had from the beginning. This old commandment is the word you have heard.

On the other hand, I am writing to you a new commandment that is truly in him and in you. For the darkness is fading away, and the true light is already shining.

I am writing to you, little children, because your sins have been forgiven on account of his name.

I am writing to you, fathers, because you have known the one who has existed from the beginning. I am writing to you, young people, because you have overcome the evil one.

Whoever says, "I love God," but hates his brother is a liar. The one who does not love his brother whom he has seen cannot love the God whom he has not seen.

If anyone sees his brother committing a sin that does not lead to death, he should pray that God would give him life. This applies to those who commit sins that do not lead to death. There is a sin that leads to death. I am not telling you to pray about that.
