We know that we have come to know him if we obey his commands. The man who says, "I know him," but does not do what he commands is a liar, and the truth is not in him. But if anyone obeys his word, God's love is truly made complete in him.
This is how we know we are in him: Whoever claims to live in him must walk as Jesus did.
Dear friends, I am not writing you a new command but an old one, which you have had since the beginning.
