What does Eph. 2:8-9 illustrate about salvation?

Ephesians 2:8-9 emphasizes that salvation is a gift from God, highlighting the core Christian doctrine of grace. These verses state that individuals are saved through faith and that this salvation is not something earned through personal effort or good deeds. Instead, it underscores the belief that humans cannot merit salvation by their works, as it is given freely by God's grace. This foundational understanding signifies that faith, rather than human merit, is the pathway to salvation. It reflects the broader theological perspective that through belief in Jesus Christ, individuals enter into a relationship with God, receiving salvation as an unearned favor rather than a reward for their achievements.
