How does God's grace relate to our faith?

God's grace is intricately linked to our faith as it is by grace that we are saved through faith (Ephesians 2:8-9). According to Romans 4, faith itself is a gift from God, not something we produce on our own. This indicates that even our ability to trust in Christ for our righteousness is a work of God's grace in our hearts. Thus, when we comprehend the depth of God's grace, it drives us to respond in faith, resting in the assurance that our righteousness comes solely from Christ's completed work on our behalf.
