How do we know that God's grace leads to repentance?

The Apostle Paul in Romans 2:4 highlights that God’s kindness, forbearance, and patience serve as a divine tool to lead sinners to repentance. This means that God's grace is not a mere sentiment, but it actively works in the hearts of His people, drawing them towards Him. The understanding is that as sinners encounter the grace of God—realizing His goodness, longsuffering, and mercy—they are compelled to respond in repentance. Such repentance is critical, as it reflects a change of heart that recognizes the gravity of sin and the necessity of turning back to God, and is evidence of a true relationship with Him.
