14 Whom did he consult for his enlightenment, and who taught him the path of justice? Who taught him knowledge, and showed him the way of understanding? 15 Even the nations are like a drop from a bucket, and are accounted as dust on the scales; see, he takes up the isles like fine dust. 16 Lebanon would not provide fuel enough, nor are its animals enough for a burnt offering. 17 All the nations are as nothing before him; they are accounted by him as less than nothing and emptiness.
18 To whom then will you liken God, or what likeness compare with 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.
