What does the Bible say about salvation being God's doing?

Salvation is emphasized in Scripture as belonging solely to God's doing rather than our own works. Psalms 118:22 states, 'The stone which the builders refused is become the headstone of the corner. This is the Lord's doing; it is marvelous in our eyes.' This notion underscores the marvelous grace and sovereignty of God in salvation. It reiterates that our redemption hinges upon His works, not ours, as affirmed in John 4:34, where Jesus says, 'My meat is to do the will of him that sent me, and to finish his work.' Therefore, salvation is a divine act, and believers are called to trust in Christ's completed work on their behalf.
