How do we know that salvation is entirely God's work?

The truth of sovereign grace is demonstrated in Ephesians 2:1, where it clearly states that we were dead in our trespasses and sins. This indicates that a spiritually dead person cannot initiate faith or make choices leading to salvation. Only God's sovereign will can bring about this change. The text further emphasizes that quickening is a divine act; God 'hath quickened us together with Christ' solely by His grace. The one responsible for our resurrection is God Himself, underscoring that salvation is from beginning to end a work of God and not dependent on human will or action.
