Nicene and Post-Nicene Fathers, Vol. V:
A Treatise on the Grace of Christ, and...: Chapter 29

Chapter 29 [XXVIII.]—When He Speaks of God’s Help, He Means It Only to Help Us Do What Without It We Still Could Do.

Again, in the first book of his Defence of the Freedom of the Will, he says: “But while we have within us a free will so strong and so stedfast against sinning, which our Maker has implanted in human nature generally, still, by His unspeakable goodness, we are further defended by His own daily help.” What need is there of such help, if free will is so strong and so stedfast against sinning? But here, as before, he would have it understood that the purpose of the alleged assistance is, that that may be more easily accomplished by grace which he nevertheless supposes may be effected, less easily, no doubt, but yet actually, without grace.
