Job 9:10

Whoever is great necessarily does great things. But the one who does great things is not necessarily great. The disciples who did great things received their ability from God. Taking an example from the human realm, I want to say that the grammarian writes correctly; but not everyone who writes correctly does so because of studies in grammar. Rather, he does so by chance and habit. Job demonstrates regarding greatness that only the one who is great makes great the things he does. Analogously and in accordance with our ability, we perceive God in the greatness of creatures and so receive an idea of God. He says this, however, so that his friends—who think there is only one reason for hardship—may consider that he who does great and dreadful things also has deep and unfathomable resolutions that are glorious. These things are filled with glory, so to speak. Paul writes something similar when he says, "O the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how inscrutable his ways! For who has known the mind of the Lord?"

Which doeth great things past finding out; yea, and wonders without number.

For then we more thoroughly compass the deeds of Divine Might, when we acknowledge that we can never compass them; we then speak with greater eloquence, when we are silent on these, being struck dumb with astonishment. Since for the describing of God's works our insufficiency finds in itself how it may put forth its tongue sufficiently, that what it cannot suitably understand, it may suitably extol by being dumb. Whence it is well said by the Psalmist, Praise Him in His mighty acts; praise Him according to His excellent greatness. For He 'praises God according to His excellent greatness,' who sees that he breaks down in the fulfilling of His praise. Therefore let him say, Which doeth great things past finding out; yea, and wonders without number: viz. 'great,' in power, 'past finding out,' in reason, 'without number,' in multitude. Therefore the works of God which he could not compass by speaking, he more eloquently defined by proving deficient. But in the review of things, why are we carried so far without ourselves, considering that we know nothing of the very thing that is done to our own selves?

Lest someone should believe that divine wisdom has manifested itself only in the things just explained, he shows next that God made many other similar things which cannot be numbered by us saying, "He makes great things," in which the wisdom of God appears praiseworthy from the uniformity of their great size. This corresponds to the text already cited, "He alone stretches out the heavens." (v.8) "Unfathomable things," because men cannot discover them as a result of their instability and yet they are still ordained by divine government. This corresponds to what he has already said, "and treads upon the waves of the sea." (v.8) "Marvelous things," whose natures men cannot consider although they are made according to reason by God. This corresponds to what he already said, "He made Arcturus," and so on. (v.9) The fact that he adds, "which cannot be numbered," must be referred to each attribute, so that men cannot count the divine actions, but God can count them who makes all things "according to number, weight, and measure." (Wisdom 11:21)
