3 And we can be sure that we know him if we obey his commandments.

4 If someone claims, “I know God,” but doesn’t obey God’s commandments, that person is a liar and is not living in the truth.

5 But those who obey God’s word truly show how completely they love him. That is how we know we are living in him.

6 Those who say they live in God should live their lives as Jesus did.
