My little children, I write these things to you so that you may not sin. If anyone sins, we have a Counselor{Greek Parakleton: Counselor, Helper, Intercessor, Advocate, and Comfortor.} with the Father, Jesus Christ, the righteous.
these things write I unto you: Although John writes with the authority of an apostle, he becomes very personal with his admonition as he changes from the apostolic "we" in chapter one to the personal, yet equally authoritative I. Another reason for writing is suggested. He had warned of the presence of sin in the lives of all Christians in chapter one. He now warns against the practice of sin as he continues the same train of thought in this chapter.
