Romans 11:34

For who hath known the mind of the Lord? - Who can pretend to penetrate the counsels of God, or fathom the reasons of his conduct? His designs and his counsels are like himself, infinite; and, consequently, inscrutable. It is strange that, with such a scripture as this before their eyes, men should sit down and coolly and positively write about counsels and decrees of God formed from all eternity, of which they speak with as much confidence and decision as if they had formed a part of the council of the Most High, and had been with him in the beginning of his ways! A certain writer, (Mr. Perkins), after having entered into all these counsels, and drawn out his black-lined scheme of absolute and eternal reprobation, with all its causes and effects; and then his light-lined scheme of absolute and eternal Election, with all its causes and effects, all deduced in the most regular and graduated order, link by link; concludes with Romans 11:33 : O the depth of the riches both of the wisdom and knowledge of God! how Unsearchable are his judgments, and his ways Past Finding Out! But this writer forgot that he had searched out God's judgments in the one case, and found out his ways in the other: and that he had given, as a proof of the success of his researches, a complete exhibition of the whole scheme! This conduct is worthy of more than mere reprehension; and yet he who differs from such opinions gives, in the apprehension of some, this proof of his being included in some of the links of the black list! We may rest with the conviction, that God is as merciful and good in all his ways, as he is wise and just. But as we cannot comprehend him, neither can we his operations, it is our place, who are the objects of his infinite mercy and kindness, to adore in silence, and to obey with alacrity and delight.

For who hath known? ... - This verse is a quotation, with a slight change, from Isaiah 40:13, "Who hath directed the Spirit of the Lord, or being his counsellor hath taught him?" It is designed to express the infinite wisdom and knowledge of God, by affirming that no being could teach him, or counsel him. Earthly monarchs have counsellors of state, whom they may consult in times of perplexity or danger. But God has no such council. He sits alone; nor does he call in any or all of his creatures to advise him. All created beings are not qualified to contribute anything to enlighten or to direct him. It is also designed to silence all opposition to his plans, and to hush all murmurings. The apostle had proved that this was the plan of God. However mysterious and inscrutable it might appear to the Jew or the Gentile, yet it was his duty to submit to God, and to confide in his wisdom, though he was not able to trace the reason of his doings.
