Grace means the free, unmerited, unexpected love of God, and all the benefits, delights, and comforts which flow from it. It means that while we were sinners and enemies we have been treated as sons and heirs.
The grace of God, says Luther, is like a flying summer shower. It has fallen upon more than one land, and passed on. Judea had it, and lies barren and dry. These Asiatic coasts had it, and flung it away.
