You know that he was revealed to take away our sins, and in him is no sin.
The second reason John gives in this verse to discourage making sin the order of our lives is couched in the words, "and in him is no sin." Sinful conduct ignores His sinless perfection. Vincent says that it means "literally, in Him sin is not. He is essentially and forever without sin" (347). In His words, deeds, life, and death, Jesus is sinlessly perfect. He has never taken a wrong step, struck a wrong note, or done a wrong deed. Once, He challenged those who had known Him from His boyhood days, "Which of you convicteth me of sin?" (John 8:46) There was not an answer to that question then, and there has not been one since. Jesus "did no sin" (1 Peter 2:22), and "in Him is no sin." He is neither a sinner nor is He sinful. What an impeccable justification for transcribing into our lives the characteristics of the wonderful Christ! To follow Him is to live on the highest possible plane of human life.
