What does the Bible say about the concept of grace?

Grace is a central theme throughout the Bible, highlighting God's unmerited favor towards sinners. In Ephesians 2:8-9, it is stated that we are saved by grace through faith and not by our works, which underscores the belief that salvation is a gift from God rather than something we achieve on our own. This grace is vividly depicted in the lives of biblical figures such as Noah, who found grace in the eyes of the Lord amidst a wicked generation (Genesis 6:8). Thus, grace serves as the means by which God justly relates to humanity while maintaining His holiness.
