Thomas Brooks addresses the distinction between true repentance and hypocritical sorrow for sin, emphasizing that while a hypocrite may feel troubled by the consequences of sin, such as damage to reputation or fear of punishment, they lack genuine mourning or hatred for sin itself. True sorrow for sin arises from an understanding of its nature and its offense against God, rather than merely its effects on oneself. Brooks calls for a deeper recognition of sin's defilement and its separation from God's holiness, urging believers to cultivate a true hatred for sin that reflects God's own nature.
