“Harden your heart.”

“The slave is not afflicted with a punishment greater than the hardening of the heart and being distant from Allah. For the Fire was created to melt the hardened heart. The most distant heart from Allah is the heart which is hardened. If the heart becomes hardened, the eye becomes dry.”

“But responsibility hardens the heart. It must.”

“I harden my glare and my heart.”

“But perhaps a heart takes experience and time to harden.”

“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. Thus God sends his word and ordinances to men which, by their abuse, prove an occasion of their hardening.”
