What does the Bible say about salvation being by divine appointment?

In Isaiah 26:12, we learn that salvation is wrought by God and appointed according to His divine will. This highlights the foundational truth in Reformed theology that salvation is not a result of human effort or initiative but rather a sovereign act of God. Ephesians 2:8-9 reinforces this by affirming that salvation is a gift from God, not a result of works, so that no one may boast. Thus, it is by His grace that we are saved, through faith, which itself is part of His divine provision.
