Charles H. Spurgeon on Psalms 81:12

So I gave them up unto their own hearts' lust. No punishment is more just or more severe than this. If men will not be checked, but madly take the bit between their teeth and refuse obedience, who shall wonder if the reins are thrown upon their necks, and they are let alone to work out their own destruction. It were better to be given up to lions than to our hearts' lusts. And they walked in their own counsels. There was no doubt as to what course they would take, for man is everywhere wilful and loves his own way, —that way being at all times in direct opposition to God's way. Men deserted of restraining grace, sin with deliberation; they consult, and debate, and consider, and then elect evil rather than good, with malice aforethought and in cool blood. It is a remarkable obduracy of rebellion when men not only run into sin through passion, but calmly "walk in their own counsels" of iniquity.
