Charles H. Spurgeon on Psalms 18:23

"Mine iniquity." A man's darling sin may change with the change of a man's condition, and some occasion that may present itself. What was Saul's and Jehu's sin before they came into the crown we know not; but surely it was wherein their lust did afterwards run out —the establishing a kingdom upon their posterity. Wantonness may be the darling of a man's youth, and worldliness the darling of his age; and a man's being raised unto honour, and having the opportunities that he had not in times past, the lust may run in another channel, he having now such an opportunity as before he never expected. —William Strong.
