Isaiah 45:18

This description of God is here added, either,

1. To detect the vanity of idols, by asserting that none was to be owned as the true God besides that one God who made the heavens and the earth, and the inhabitants thereof. Or,

2. To demonstrate God's sufficiency to fulfil all these glorious promises made to his church, because he made the world of nothing, and upholds it by the word of his power; and withal to discover God's goodness to mankind, inasmuch as he did not create the earth in vain, but for the use and comfort of men, that it might be a fit habitation for them; whence it was easy to infer that God would much more be gracious to his own people.
