4 Kings (2 Kings) Chapter 10
(Kg2 10:1-14) Ahab's sons and Ahaziah's brethren put to death.
(Kg2 10:15-28) Jehu destroys the worshippers of Baal.
(Kg2 10:29-36) Jehu follows Jeroboam's sins.
In the most awful events, though attended by the basest crimes of man, the truth and justice of God are to be noticed; and he never did nor can command any thing unjust or unreasonable. Jehu destroyed all that remained of the house of Ahab; all who had been partners in his wickedness. When we think upon the sufferings and miseries of mankind, when we look forward to the resurrection and last judgment, and think upon the vast number of the wicked waiting their awful sentence of everlasting fire; when the whole sum of death and misery has been considered, the solemn question occurs, Who slew all these? The answer is, SIN. Shall we then harbour sin in our bosoms, and seek for happiness from that which is the cause of all misery?
Is thine heart right? This is a question we should often put to ourselves. I make a fair profession, have gained a reputation among men, but, is my heart right? Am I sincere with God? Jehonadab owned Jehu in the work, both of revenge and of reformation. An upright heart approves itself to God, and seeks no more than his acceptance; but if we aim at the applause of men, we are upon a false foundation. Whether Jehu looked any further we cannot judge. The law of God was express, that idolaters were to be put to death. Thus idolatry was abolished for the present out of Israel. May we desire that it be rooted out of our hearts.
It is justly questionable whether Jehu acted from a good principle, and whether he did not take some false steps in doing it; yet no services done for God shall go unrewarded. But true conversion is not only from gross sin, but from all sin; not only from false gods, but from false worships. True conversion is not only from wasteful sins, but from gainful sins; not only from sins which hurt our worldly interests, but from those that support and befriend them; in forsaking which is the great trial whether we can deny ourselves and trust God. Jehu showed great care and zeal for rooting out a false religion, but in the true religion he cared not, took no heed to please God and do his duty. Those that are heedless, it is to be feared, are graceless. The people were also careless, therefore it is not strange that in those days the Lord began to cut Israel short. They were short in their duty to God, therefore God cut them short in their extent, wealth, and power.
