“Lord, depart from me because I am a sinful man!” What is a sinful man? A sinful man is a person who lives life in the way he or she wants to without regard to anything the Lord wants. In other words, that “want to” is contrary to the Lord’s way. In my view, it’s not any more complicated than that. A sinful person is not one who necessarily lives life in an overly vile way, but one who lives life in a different way than the Lord’s. For the Christian, presumably the life one has chosen to live is expressed by Paul himself: “I have been crucified with Christ; and it is no longer I that live, but Christ liveth in me: and that life which I now live in the flesh I live in faith, the faith which is in the Son of God, who loved me, and gave himself up for me (Gal. 2:20, ASV).
Think about what Paul is saying. First, his life without Christ is now dead; second, the life he has chosen to live is the life of Christ; third, he understands what it is Jesus did for him and for all those who love Him, therefore he chose to serve the Almighty. If we do not embrace the life of Jesus as Paul expressed it here, we are only kidding (or deceiving) ourselves that all is well. Paul wrote to the Corinthians in his second letter, “Try your own selves, whether ye are in the faith; prove your own selves. Or know ye not as to your own selves, that Jesus Christ is in you? unless indeed ye be reprobate” (2 Cor. 13:5). How are you living your life? RT
