Personally, I could never have overcome my own sinfulness. I tried and failed. My evil tendencies were too much for me until, in the belief that Christ died for me, I cast my guilty soul on Him. And then I received a conquering principle by which I overcame my sinful self. The doctrine of the cross can be used to slay sin like the old warriors used their huge two-handed swords and mowed down their foes at every stroke. There is nothing like faith in the sinner’s Friend; it overcomes all evil. 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 which slew 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?
—Charles H. Spurgeon
