How does God's grace relate to free will?

The relationship between God's grace and free will is fundamental in Reformed theology. Grace is defined as unmerited favor, and it is through grace that we are saved. Ephesians 2:8-9 outlines that faith is a gift from God, clearly asserting that it is not from ourselves. This signifies that human will is entirely dependent on God's grace, effectively refuting the concept of free will in the salvific process. Our acknowledgment of our sinful nature and need for His mercy leads us to understand that it is ultimately God's sovereign grace that carries us to true belief and salvation.
