How do we know salvation is a sovereign act of God?

In the context of God’s reign, salvation is consistently attributed to the sovereign will of God. John 5 articulates that 'the Father judges no one, but has committed all judgment to the Son,' illustrating that Jesus, as the sovereign Lord, holds power over human salvation. Psalm 72 supports this by declaring, 'He shall deliver the needy,' indicating that God actively saves those who recognize their helplessness. Thus, scriptural evidence confirms that only through God’s sovereign grace can salvation be accomplished, as we can do nothing to earn it ourselves.
