Job 33 - Matthew Henry's Concise Commentary on the Bible

God calls men to repentance.

God speaks to us by conscience, by providences, and by ministers; of all these Elihu discourses. There was not then, that we know of, any Divine revelation in writing, though now it is our principal guide. When God designs men's good, by the convictions and dictates of their own consciences, he opens the heart, as Lydia's, and opens the ears, so that conviction finds or forces its way in. The end and design of these admonitions are to keep men from sin, particularly the sin of pride.

While sinners are pursuing evil purposes, and indulging their pride, their souls are hastening to destruction. That which turns men from sin, saves them from hell. What a mercy it is to be under the restraints of an awakened conscience! (Job 33:19-28)
