What does the Bible say about salvation being all of grace?

Salvation is fundamentally a work of God's grace, as emphasized in Ephesians 6:18-20. Throughout scripture, it is clear that no one is saved due to their own choices or actions; it is entirely God's design and sovereign will. Ephesians 1:4-5 highlights that God chose us in Christ before the foundation of the world, demonstrating that salvation originates solely from His divine initiative and mercy. This is a cornerstone of Reformed theology, which holds that our salvation is rooted in God's grace alone, rather than any merit on our part.
