Why is being broken over sin important for Christians?

A true believer's awareness of their sinfulness is essential in the Christian life. The Apostle Paul exemplified this in Romans 7, where he lamented his struggle with sin, declaring, 'O wretched man that I am!' Recognizing one's own sin leads to a deeper understanding of the need for God's grace and empowers believers to lean wholly on the finished work of Christ for salvation. Without a profound acknowledgment of our sinful condition and a corresponding sorrow for it, one risks being a counterfeit believer who lacks true faith. This brokenness ultimately drives Christians to seek reconciliation and cleansing through the blood of Christ, as illustrated in Psalm 51 where David cried for God's mercy.
