The Difficulty of Discernment

"It is always much more difficult for Christians to detect a fundamentally sinful attitude in other Christians than in pagans—especially if that attitude is endemic to contemporary society, thereby reducing or eliminating the 'shock' force of that sin."

—D. A. Carson, From Triumphalism to Maturity: An Exposition of 2 Corinthians 10–13 (Grand Rapids: Baker, 1984), 20.
