Thomas Brooks emphasizes that recognizing one's own sinfulness and wretchedness is essential for true godliness. He asserts that before one can seek the mercy of God, they must first acknowledge their dire state as children of wrath and enemies of God. The realization of being near to hell is the first step towards heaven, as it compels individuals to seek the physician of souls, Jesus Christ. Without this awareness of their spiritual wounds and diseases, people will not value or desire the healing that Christ offers. Brooks calls for a deep self-examination to understand one's need for divine mercy.
