"Irreplaceable"

Who has measured the waters in the hollow of his hand, marked off the heavens with a [nine-inch] span, enclosed the dust of the earth in a measure, and weighed the mountains in scales and the hills in a balance?

Who has directed the Spirit of the Lord, or as His counselor has taught Him? With whom did He take counsel, that instruction might be given Him? Who taught Him the path of justice and taught Him knowledge and showed Him the way of understanding?

Behold, the nations are like a drop from a bucket and are counted as small dust on the scales; behold, He takes up the isles like a very little thing. And all Lebanon’s [forests] cannot supply sufficient fuel, nor all its wild beasts furnish victims enough to burn sacrifices [worthy of the Lord]. All the nations are as nothing before Him; they are regarded by Him as less than nothing and emptiness (waste, futility, and worthlessness).

Therefore to whom then will you liken God? Or with what likeness will you compare Him? Isaiah 40:12-14)

Man Can Teach God Nothing

Men sometimes suppose that they discover new scientific truths, but they cannot teach God anything, because our God is a God of infinite knowledge. Satan well knows that the worship of the living God elevates, ennobles and exalts. He knows that the worship of idols cannot elevate man but he leads them to worship their graven image! A workman casts it, and a goldsmith overlays it with gold and casts silver chains for it. Children whom God have reared and brought up, turn against God and rebelled against him.

Said the Lord, The ox knows its owner, and the donkey its master's crib, but my cildren, does not know, my people do not understand.” they are a people laden with iniquity, offspring of evildoers, children who deal corruptly! They have forsaken me, they have despised the Holy God, they are utterly estranged; and continue to rebel.

Incomparable God

God is irreplaceable, incomparable, "Let us see how great our God is, and fear him; for His power is unlimited, and what no creature can compare with, much less contend with. He has a vast reach. View the celestial globe, and you are astonished at the extent of it; but the great God metes the heavens with a span; to him they are but a hand-breadth, so large-handed is he. View the terraqueous globe, and he has the command of that too. All the waters in the world he can measure in the hollow of his hand, where we can hold but a little water; and the dry land he easily manages, for he comprehends the dust of the earth in a measure, or with his three fingers; it is no more to him than a pugil, or that which we take up between our thumb and two fingers. 

He has a vast strength, and can as easily move mountains and hills as the tradesman heaves his goods into the scales and out of them again; he poises them with his hand as exactly as if he weighed them in a pair of balances. This may refer to the work of creation, when the heavens were stretched out as exactly as that which is spanned, and the earth and waters were put together in just proportions, as if they had been measured, and the mountains made of such a weight as to serve for ballast to the globe, and no more. Or it may refer to the work of providence (which is a continued creation) and the consistency of all the creatures with each other. 

His wisdom is unsearchable, and what no creature can give either information or direction to, As none can do what God has done and does, so none can assist him in the doing of it or suggest any thing to him which he thought not of. When the Lord by his Spirit made the world (Job. 26:13) there was none that directed his Spirit, or gave him any advice, either what to do or how to do it. Nor does he need any counsellor to direct him in the government of the world, nor is there any with whom he consults, as the wisest kings do with those that know law and judgment, Esther. 1:13.

Irreplaceable

God needs not to be told what is done, for he knows it perfectly; nor needs he be advised concerning what is to be done, for he knows both the right end and the proper means. The nations of the world are nothing in comparison of him. All the great and mighty nations of the earth, kings the most pompous, kingdoms the most populous, both the most wealthy; take the isles, the multitude of them: Before him, when they stand in competition with him or in opposition to him, they are as a drop of the bucket compared with the vast ocean, or the small dust of the balance (which does not serve to turn it, and therefore is not regarded, it is so small) in comparison with all the dust of the earth. He takes them up, and throws them away from him, as a very little thing, not worth speaking of. They are all in his eye as nothing, as if they had no being at all; for they add nothing to his perfection and all-sufficiency. They are counted by him, and are to be counted by us in comparison of him, less than nothing, and vanity."
