Grace

Grace is a theological term present in many religions, defined as the divine influence which operates in humans to regenerate and sanctify, to inspire virtuous impulses, and to impart strength to endure trial and resist temptation; and as an individual virtue or excellence of divine origin.

Description
In Christianity, grace is the free and unmerited favour of God as manifested in the salvation of sinners and the bestowing of blessings. Common Christian teaching is that grace is unmerited mercy (favor) that God gave to humanity by sending his son to die on a cross, thus delivering eternal salvation.
