Why do we need God's grace for salvation?

God's grace is essential for salvation because, as sinful beings, we lack the capacity to redeem ourselves. Ephesians 2:8-9 emphasizes that it is by grace we are saved through faith, and this is not our own doing; it is the gift of God. Without this grace, we would remain lost and under damnation for sin. Grace signifies unmerited favor, illustrating that it is only through God’s intervention, not our efforts, that we can be freed from the penalty of sin and granted eternal life. This understanding is foundational for recognizing the depth of Christ's work on our behalf as the fulfillment of God's grace.
