1 My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One.
2 He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.

Love and Hatred for Fellow Believers

3 We know that we have come to know him if we keep his commands.
4 Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person.
5 But if anyone obeys his word, love for Goda is truly made complete in them. This is how we know we are in him:
6 Whoever claims to live in him must live as Jesus did.
7 Dear friends, I am not writing you a new command but an old one, which you have had since the beginning. This old command is the message you have heard.
8 Yet I am writing you a new command; its truth is seen in him and in you, because the darkness is passing and the true light is already shining.
9 Anyone who claims to be in the light but hates a brother or sisterb is still in the darkness.
10 Anyone who loves their brother and sisterc lives in the light, and there is nothing in them to make them stumble.
