Charles Spurgeon, sermon 1068:
Only let a man once feel sin for half-an-hour, really feel its tortures, and I warrant you he could prefer to dwell in a pit of snakes than to live with his sins. Remember that cry of David, “My sin is ever before me” [Psalm 51:3]; he speaks as though it haunted him. He shut his eyes but he still saw its hideous shape; he sought his bed, but like a nightmare it weighed upon his breast; he rose, and it rose with him; he tried to shake it off among the haunts of men, in business and in pleasure, but like a blood-sucking vampire it clung to him. Sin was ever before him, as though it were painted on his eye-balls, the glass of his soul’s window was stained with it. He sought his closet but could not shut it out, he sat alone but it sat with him; he slept, but it cursed his dreams. His memory it burdened, his imagination it lit up with lurid flame, his judgment it armed with a ten-thonged whip, his expectations it shrouded in midnight gloom. A man needs no worse hell than his own sin, and an awakened conscience.
What is there to say after reading that quote except to sing: “Hallelujah! All I have is Christ / Hallelujah! Jesus is my life.”
