Why is God's grace essential for redemption?

In Ephesians 2:4-5, we learn that God, rich in mercy, saved us by grace through faith. This grace is not a result of our works but a divine gift that humbles us and removes any grounds for boasting (Ephesians 2:8-9). By recognizing that we were by nature children of wrath (Ephesians 2:3), we see that grace is vital for our redemption, emphasizing that salvation is entirely God's work. This grace leads to new life, encouraging believers to respond in faith and obedience as a reflection of their transformed status as God's children.
