What does the Bible say about the sovereignty of God in salvation?

Scripture clearly shows that salvation is not initiated by our own decisions but is instead a work of God's sovereign grace. In Acts 16:14, we see Lydia's heart was opened by the Lord, demonstrating that God actively draws the hearts of those He has chosen to hear and believe the gospel. Additionally, Romans 10 emphasizes that faith comes by hearing the Word of God, underscoring the necessity of divine action in the heart for genuine belief to occur. This reflects the essence of the Reformed understanding that God is the one who initiates and completes the process of salvation for His people.
