Thomas Brooks emphasizes that our sorrows and sufferings are often a direct result of our sins, urging believers to reflect on their actions rather than complain about their afflictions. He encourages Christians to recognize that when they face hardships, it is their own sinful nature that has led to these trials. Brooks calls for a return to the Lord, advocating for patience and self-examination in the face of God's discipline. He highlights the importance of acknowledging our pride, worldliness, and backsliding as contributors to our suffering, ultimately pointing to the need for repentance and humility.
