“No one sins out of duty. We sin because we believe the deceitful promises that sin makes. The Bible warns ‘that none of you may be hardened by the deceitfulness of sin’ (Hebrews 3:13). The promises of sin are lies… We sever the lifeline of sin by the power of a superior promise.”
–John Piper, Battling Unbelief (Colorado Springs, Co.: Multnomah Publishers, 2007), pp. 16-17.
