Those things which men call fortuitous events, are proofs of divine providence

Also his providence, power, and wisdom.

8. To this purpose the Psalmist, (Psalm 107) mentioning how God, in a wondrous manner, often brings sudden and unexpected succor to the miserable when almost on the brink of despair, whether in protecting them when they stray in deserts, and at length leading them back into the right path, or supplying them with food when famishing for want, or delivering them when captive from iron fetters and foul dungeons, or conducting them safe into harbor after shipwreck, or bringing them back from the gates of death by curing their diseases, or, after burning up the fields with heat and drought, fertilizing them with the river of his grace, or exalting the meanest of the people, and casting down the mighty from their lofty seats: — the Psalmist, after bringing forward examples of this description, infers that those things which men call fortuitous events, are so many proofs of divine providence, and more especially of paternal clemency, furnishing ground of joy to the righteous, and at the same time stopping the mouths of the ungodly. But as the greater part of mankind, enslaved by error, walk blindfold in this glorious theater, he exclaims that it is a rare and singular wisdom to meditate carefully on these works of God, which many, who seem most sharp-sighted in other respects, behold without profit. It is indeed true, that the brightest manifestation of divine glory finds not one genuine spectator among a hundred. Still, neither his power nor his wisdom is shrouded in darkness. His power is strikingly displayed when the rage of the wicked, to all appearance irresistible, is crushed in a single moment; their arrogance subdued, their strongest bulwarks overthrown, their armor dashed to pieces, their strength broken, their schemes defeated without an effort, and audacity which set itself above the heavens is precipitated to the lowest depths of the earth. On the other hand, the poor are raised up out of the dust, and the needy lifted out of the dung hill, (Psalm 113:7,) the oppressed and afflicted are rescued in extremity, the despairing animated with hope, the unarmed defeat the armed, the few the many, the weak the strong. The excellence of the divine wisdom is manifested in distributing everything in due season, confounding the wisdom of the world, and taking the wise in their own craftiness, (1 Corinthians 3:19;) in short, conducting all things in perfect accordance with reason.
