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.
Jesus Christ the righteous - One who is eminently righteous himself, and who possesses the means of rendering others righteous. It is an appropriate feeling when we come before God in his name, that we come pleading the merits of one who is eminently righteous, and on account of whose righteousness we may be justified and saved.
