14 What expert would he have gone to for advice, what school would he attend to learn justice? What god do you suppose might have taught him what he knows, showed him how things work? 15 Why, the nations are but a drop in a bucket, a mere smudge on a window. Watch him sweep up the islands like so much dust off the floor! 16 There aren't enough trees in Lebanon nor enough animals in those vast forests to furnish adequate fuel and offerings for his worship. 17 All the nations add up to simply nothing before him - less than nothing is more like it. A minus.
18 So who even comes close to being like God? To whom or what can you compare him?
Matthew Henry's Commentary on Isaiah 40:14-18
Commentary on Isaiah 40:12-17
(Read Isaiah 40:12-17)
All created beings shrink to nothing in comparison with the Creator. When the Lord, by his Spirit, made the world, none directed his Spirit, or gave advice what to do, or how to do it. The nations, in comparison of him, are as a drop which remains in the bucket, compared with the vast ocean; or as the small dust in the balance, which does not turn it, compared with all the earth. This magnifies God's love to the world, that, though it is of such small account and value with him, yet, for the redemption of it, he gave his only-begotten Son, John 3:16. The services of the church can make no addition to him. Our souls must have perished for ever, if the only Son of the Father had not given himself for us.
Commentary on Isaiah 40:18-26
(Read Isaiah 40:18-26)
Whatever we esteem or love, fear or hope in, more than God, that creature we make equal with God, though we do not make images or worship them. He that is so poor, that he has scarcely a sacrifice to offer, yet will not be without a god of his own. They spared no cost upon their idols; we grudge what is spent in the service of our God. To prove the greatness of God, the prophet appeals to all ages and nations. Those who are ignorant of this, are willingly ignorant. God has the command of all creatures, and of all created things. The prophet directs us to use our reason as well as our senses; to consider who created the hosts of heaven, and to pay our homage to Him. Not one fails to fulfil his will. And let us not forget, that He spake all the promises, and engaged to perform them.
