Complete Commentary on the Whole Bible, by Matthew Henry, at sacred-texts.com
(Job 42:1-6) Job humbly submits unto God.
(Job 42:7-9) Job intercedes for his friends.
(Job 42:10-17) His renewed prosperity.
Job was now sensible of his guilt; he would no longer speak in his own excuse; he abhorred himself as a sinner in heart and life, especially for murmuring against God, and took shame to himself. When the understanding is enlightened by the Spirit of grace, our knowledge of Divine things as far exceeds what we had before, as the sight of the eyes excels report and common fame. By the teachings of men, God reveals his Son to us; but by the teachings of his Spirit he reveals his Son in us, Gal 1:16, and changes us into the same image, Co2 3:18. It concerns us to be deeply humbled for the sins of which we are convinced. Self-loathing is ever the companion of true repentance. The Lord will bring those whom he loveth, to adore him in self-abasement; while true grace will always lead them to confess their sins without self-justifying.
After the Lord had convinced and humbled Job, and brought him to repentance, he owned him, comforted him, and put honour upon him. The devil had undertaken to prove Job a hypocrite, and his three friends had condemned him as a wicked man; but if God say, Well done, thou good and faithful servant, it is of little consequence who says otherwise. Job's friends had wronged God, by making prosperity a mark of the true church, and affliction a certain proof of God's wrath. Job had referred things to the future judgment and the future state, more than his friends, therefore he spake of God that which was right, better than his friends had done. And as Job prayed and offered sacrifice for those that had grieved and wounded his spirit, so Christ prayed for his persecutors, and ever lives, making intercession for the transgressors. Job's friends were good men, and belonged to God, and He would not let them be in their mistake any more than Job; but having humbled him by a discourse out of the whirlwind, he takes another way to humble them. They are not to argue the matter again, but they must agree in a sacrifice and a prayer, and that must reconcile them, Those who differ in judgment about lesser things, yet are one in Christ the great Sacrifice, and ought therefore to love and bear with one another. When God was angry with Job's friends, he put them in a way to make peace with him. Our quarrels with God always begin on our part, but the making peace begins on his. Peace with God is to be had only in his own way, and upon his own terms. These will never seem hard to those who know how to value this blessing: they will be glad of it, like Job's friends, upon any terms, though ever so humbling. Job did not insult over his friends, but God being graciously reconciled to him, he was easily reconciled to them. In all our prayers and services we should aim to be accepted of the Lord; not to have praise of men, but to please God.
In the beginning of this book we had Job's patience under his troubles, for an example; here, for our encouragement to follow that example, we have his happy end. His troubles began in Satan's malice, which God restrained; his restoration began in God's mercy, which Satan could not oppose. Mercy did not return when Job was disputing with his friends, but when he was praying for them. God is served and pleased with our warm devotions, not with our warm disputes. God doubled Job's possessions. We may lose much for the Lord, but we shall not lose any thing by him. Whether the Lord gives us health and temporal blessings or not, if we patiently suffer according to his will, in the end we shall be happy. Job's estate increased. The blessing of the Lord makes rich; it is he that gives us power to get wealth, and gives success in honest endeavours. The last days of a good man sometimes prove his best, his last works his best works, his last comforts his best comforts; for his path, like that of the morning light, shines more and more unto the perfect day.
