Note, 1. Many need severe rebukes. Some children are so obstinate that their parents can do no good with them without sharp correction; some criminals must feel the rigour of the law and public justice; gentle methods will not work upon them; they must be beaten black and blue. And the wise God sees that his own children sometimes need very sharp afflictions. 2. Severe rebukes sometimes do a great deal of good, as corrosives contribute to the cure of a wound, eating out the proud flesh. The rod drives out even that foolishness which was bound up in the heart, and cleanses away the evil there. 3. Frequently those that most need severe rebukes can worse bear them. Such is the corruption of nature that men are as loth to be rebuked sharply for their sins as to be beaten till their bones ache. Correction is grievous to him that forsakes the way, and yet it is good for him, Heb 12:11.
