Augutines Doctrine of Grace

"Sinful man depends, for his recovery to good and to God, entirely on the free grace of God; this grace is therefore indispensable, prevenient, irresistible, indefectible; and, being thus the free grace of God, must have lain, in all the details of its conference and working, in the intention of God from all eternity.”
