How do we know salvation is solely of God?

Sovereign grace theology emphasizes that salvation is entirely the work of God, as articulated in numerous Scripture passages. Paul writes in Ephesians 2:8-9 that we are saved by grace through faith, and this is not of ourselves; it is the gift of God, not by works, so that no one can boast. Any doctrine that introduces a human role in salvation detracts from God's glory by suggesting that human effort is necessary. This understanding is crucial for recognizing God's sovereignty in our salvation. It helps believers appreciate the depth of God's love and grace in choosing and saving His people purely by His will and purpose.
