How does God make a difference in the lives of sinners?

The difference in the lives of sinners is attributed solely to God’s sovereign grace. In the case of the two thieves, one exhibited faith and was saved while the other remained in disbelief. This points to the nature of divine election where God chooses whom He will save, impacting their hearts and granting them faith (Ephesians 1:4-5). As seen in Romans 9, God's choice is not based on human works but rather on His mercy. God's intervention through the Holy Spirit enable sinners to respond in faith, just as the one thief did, highlighting that all glory for salvation belongs to God alone.
