6 Those who say they live in God should live their lives as Jesus did.
7 Dear friends, I am not writing a new commandment for you; rather it is an old one you have had from the very beginning. This old commandment—to love one another—is the same message you heard before.
8 Yet it is also new. Jesus lived the truth of this commandment, and you also are living it. For the darkness is disappearing, and the true light is already shining.
9 If anyone claims, “I am living in the light,” but hates a fellow believer, that person is still living in darkness.
10 Anyone who loves a fellow believer is living in the light and does not cause others to stumble.
11 But anyone who hates a fellow believer is still living and walking in darkness. Such a person does not know the way to go, having been blinded by the darkness.
12 I am writing to you who are God’s childrenbecause your sins have been forgiven through Jesus.
