Those who are pleasing to God testify with the penitent tax-collector in the Temple: “God, be merciful to me, the sinner!” (Luke 18:13). Augustine pleaded, “Lord, save me from that wicked man, myself.” John Knox, perhaps the greatest preacher in the history of Scotland, confessed, “In youth, in middle age and now after many battles, I find nothing in me but corruption.” John Wesley wrote, “I am fallen short of the glory of God, my whole heart is altogether corrupt and abominable, and consequently my whole life being an evil tree cannot bring forth good fruit.” His brother Charles, who penned so many great hymns, confessed, “Vile and full of sin I am.” Augustus Toplady, who wrote the beloved hymn “Rock of Ages,” said of himself, “Oh, that such a wretch as I should ever be tempted to think highly of himself. I am myself nothing but sin and weakness, in whose flesh naturally dwells no good thing.”
