Jonathan Edwards

In this sense, I utterly deny God to be the Author of Sin; rejecting such an imputation on the Most High, as what is infinitely to be abhorred; and deny any such thing to be the consequence of what I have laid down.

When God is here spoken of as hardening some of the children of men, it is not to be understood that God by any positive efficiency hardens any man's heart. There is no positive act in God, as though he put forth any power to harden the heart. To suppose any such thing would be to make God the immediate author of sin. God is said to harden men in two ways: by withholding the powerful influences of his Spirit, without which their hearts will remain hardened, and grow harder and harder; in this sense he hardens them, as he leaves them to hardness. And again, by ordering those things in his providence which, through the abuse of their corruption, become the occasion of their hardening.

As there is a vast difference between the sun being the cause of the lightsomeness and warmth of the atmosphere, and the brightness of gold and diamonds, by its presence and positive influence; and its being the occasion of darkness and frost, in the night, by its motion, whereby it descends below the horizon. The motion of the sun is the occasion of the latter kind of events; but it is not the proper cause, efficient, or producer of them; though they are necessarily consequent on that motion, under such circumstances: no more is any action of the Divine Being the cause of the evil of men's Wills.

In order to account for a sinful corruption of nature, yea, a total native depravity of the heart of man, there is not the least need of supposing any evil quality, infused, implanted, or wrought into the nature of man, by any positive cause, or influence whatsoever, either from God, or the creature; or of supposing, that man is conceived and born with a fountain of evil in his heart, such as is any thing properly positive.
