How do we know that grace is a gift from God?

Grace is fundamentally understood as unearned favor from God. In Genesis 6:8, it is noted that 'Noah found grace in the eyes of the Lord,' highlighting that grace is a divine gift, not a reward for works. This reflects God's mercy and kindness extended to undeserving individuals. Grace signifies goodwill and acceptance that comes purely from God's decision to show favor upon whom He wills. This means that no one can claim to have earned God's grace, as it is given freely from His heart. The nature of grace emphasizes God's sovereignty and His right to dispense mercy according to His pleasure.
