Adam's evil use of his free will

"It was by the evil use of his free will that man destroyed both it and himself." - Augustine

The Value of Christ

"Christ is not valued at all, unless he is valued above all" ~ Augustine

Foreknowledge

"Here certainly, there is no place for the vain argument of those who defend the foreknowledge of God against the grace of God, and accordingly maintain that we were elected before the foundation of the world because God foreknew that we would be good, not that He Himself would make us good. This is not the language of Him who said, 'You did not choose Me, but I chose you' (John 15:16)."
-Augustine

Augustine on Earthly Riches

"From the goods which they distributed to others and so placed in greater safety, they derived more happiness than they incurred sorrow from the goods which they anxiously hoarded and so lost more easily. Nothing could be really lost on earth save what one would be ashamed to take to heaven."
-Augustine
