If Christ has died for me - ungodly as I am, without strength as I am - then I can no longer live in sin, but must arouse myself to love and serve Him who has redeemed me. I cannot trifle with the evil that killed my best Friend. I must be holy for his sake. How can I live in sin when He has died to save me from it?
