“Turn with me to Job 37:12,13, where we find two purposes of God for disasters.
1. The first Divine purpose for disaster is for correction or literally, the rod (Job 37:13a). Here God uses the cloud filled with rain to burst forth in judgment upon wicked and godless men in bringing floods (reminiscent of the deluge at Noah’s time) that destroy the crops, the livelihood, and the life of man. No doubt, under this heading we might include any disaster by which God would bring temporal judgment upon wicked people and nations of this world who have rejected, despised, or forgotten the Lord and His Christ, the Moral Law and Gospel of the Lord and His Christ, and the only true religion of the Lord and His Christ, biblical Christianity. This purpose displays the vindictive justice of a holy God in pouring forth His wrath upon the wicked people and wicked nations of the world as a foretaste of the everlasting judgment to come (Romans 1:18—note the present, on-going, and continuous revelation of God’s wrath in the world upon the wicked who suppress the truth God in unrighteousness, which is displayed in many ways, but must include the judgments God brings by way of disasters and calamities upon people and nations for their rebellion against the Lord and His Christ; see Psalm 2:10-12; Psalm 79:6)…
3. The second Divine purpose for disaster that comes from the cloud filled with rain in Job 37:13 is “for mercy.” Here it would seem that God brings the flood that destroys the crops and livelihood of man not only to judge impenitent people and nations, but also to show mercy to people and nations whose eyes in such disasters are opened to see the vanity of trusting in the things of this earth as the source of their safety and security, as the source of their joy and happiness, and as the source of their peace and comfort. God brings disaster so as to have the ultimate mercy upon people and nations by enlightening their minds to behold the mercy of God in Christ Jesus so that they embrace Christ by faith alone and are set free from righteous God’s judgment forever.”
