“Come now, and let us reason together, saith the LORD: though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool.” —Isaiah 1:18
You have asked to be a disciple of Christ in your prayer. I ask you again, how is it reasonable that you should be recognized as a disciple of Christ if you will not imitate his character, and if you do not desire to obey his commands? This man a disciple of Christ! And yet he remains an habitual drunkard, or carries on a dishonest trade, or lives in unchastity! Can he really be a Christian? Every hallowed name forbids. Such a man is a servant of the devil, not of Jesus. His servants ye are whom ye obey; there is no mistake about that matter. He that doeth sin is the servant of sin. If you yield yourselves unto evil then ye are the servants of evil, and the wrath of God abides upon you.
—Charles H. Spurgeon (1834-1892)
Delivered Sunday Morning, February 13, 1876 at the Metropolitan Tabernacle, Newington
