Mormons believe that all blessings from God come in the form of a gift. For instance, the forgiveness of sins, grace, and redemption are gifts from God. However, receiving these gifts is entirely dependent upon their obedience. "There is a law, irrevocably decreed in heaven before the foundations of this world, upon which all blessings are predicated -- And when we obtain any blessing from God, it is by obedience to that law upon which it is predicated" (D&C 130:20-21).
Biblical Christianity teaches that God’s greatest gifts (i.e. forgiveness, eternal life) are unconditional. They are undeserved gifts in the truest sense of the word. It further teaches that God often gives many unmerited earthly blessings.
