How does God's sovereignty affect salvation according to Scripture?

Scripture portrays God's sovereignty as fundamental to the plan of salvation. Ephesians 1:4-5 states that God chose us in Christ before the foundation of the world, signifying that our salvation is rooted in His divine purpose and not a result of our own decision-making. The Bible also describes how God has mercy on whom He wills, intimating that His grace is freely given according to His will and not according to human merit or effort. Knowing that salvation is God's work reassures believers that their standing before Him is secure, as it rests solely on His promises and character, rather than fluctuating human deeds.
