How do we know salvation is truly from God?

Salvation is distinctly described in the Bible as God's work from beginning to end. As Paul articulated in 1 Thessalonians, 'Salvation is of the Lord,' encapsulating the total dependence of believers on God's grace. Scripture teaches that God is both the author and finisher of our faith (Hebrews 12:2), showing the sovereign grace that undergirds our redemption. The totality of salvation rests solely on God’s election, redemption through Christ, and the work of the Holy Spirit, ensuring that all who believe are truly saved by God's plan.
