How do we know God's grace is essential for redemption?

The necessity of God's grace for redemption is central to the Reformed understanding of salvation. As illustrated in the story of David, who realized that his future lay solely in God's hands, we see that true faith acknowledges our inability to achieve righteousness on our own. According to Ephesians 2:8-9, we are saved by grace through faith, which is not from ourselves but is a gift of God. This grace enables us to recognize our complete dependence on the mercy of God. Without His grace intervening in our lives, we remain in our sinful state, lost and condemned. Ultimately, grace is what empowers us to turn from our rebellion and embrace the salvation offered in Jesus Christ, affirming that our hope is rooted entirely in His sovereign will and goodness.
