Thomas Brooks emphasizes that true repentance is a continuous process of turning away from sin and drawing closer to God. It involves a genuine recognition of sin, deep sorrow, and a heartfelt loathing of both sin and oneself. Repentance requires a transformation that cleanses the mind, heart, and life, challenging the natural tendency of self-love and self-exaltation. Brooks highlights that true repentance is about dying to sin daily and living for God, which can be a difficult journey for those who are accustomed to self-admiration.
