How does the Bible define grace?

Grace, in the biblical sense, refers to the unmerited favor of God upon those who do not deserve it. It operates contrary to the law's demands, which bring about death, as evidenced by the water turned to blood in Exodus. Paul describes grace as a means by which believers are saved, not by their actions but solely through faith in Christ (Ephesians 2:8-9). The transforming effects of grace are further reflected in Christ's turning of water into wine at the wedding of Cana, symbolizing abundant life and joy, which God's grace freely provides to His elect. The juxtaposition of law and grace highlights the beauty of the gospel.
