The Lord, he is the God - The people thus pronounced the matter to be clearly and certainly decided. Baal was overthrown; he was proved to be no god at all. The Lord Yahweh, He, and He alone, is God. Him would they henceforth acknowledge, and no other.

Fell on their faces - Struck with awe and reverence at the sight of this incontestable miracle.

And they said - We should translate the words thus: Jehovah, He is the God! Jehovah, He is the God! Baal is not the God; Jehovah alone is the God of Israel.

As our term Lord is very equivocal, we should every where insert the original word יהוה, which we should write Yeve or Yeheveh, or Yahvah or Yehueh, or, according to the points, Yehovah.

And when all the people saw it, they fell on their faces,.... In reverence of God, astonished at the miracle wrought, ashamed of themselves and their sins, particularly their idolatry, that they should turn their backs on the true God, and follow idols:

and they said, the Lord, he is the God, the Lord, he is the God; which acknowledgment of God, as the true God, in opposition to Baal, is repeated, to show their firm belief and strong assurance of it.

And when all the people saw it, they fell on their faces: and they said, The LORD, he is the God; the LORD, he is the God.

18:39 They fell - In acknowledgment of the true God. He is God - He alone; and Baal is a senseless idol. And they double the words, to note their abundant satisfaction and assurance of the truth of their assertion.

18:21-40 Many of the people wavered in their judgment, and varied in their practice. Elijah called upon them to determine whether Jehovah or Baal was the self-existent, supreme God, the Creator, Governor, and Judge of the world, and to follow him alone. It is dangerous to halt between the service of God and the service of sin, the dominion of Christ and the dominion of our lusts. If Jesus be the only Saviour, let us cleave to him alone for every thing; if the Bible be the world of God, let us reverence and receive the whole of it, and submit our understanding to the Divine teaching it contains. Elijah proposed to bring the matter to a trial. Baal had all the outward advantages, but the event encourages all God's witnesses and advocates never to fear the face of man. The God that answers by fire, let him be God: the atonement was to be made by sacrifice, before the judgment could be removed in mercy. The God therefore that has power to pardon sin, and to signify it by consuming the sin-offering, must needs be the God that can relieve from the calamity. God never required his worshippers to honour him in the manner of the worshippers of Baal; but the service of the devil, though sometimes it pleases and pampers the body, yet, in other things, really is cruel to it, as in envy and drunkenness. God requires that we mortify our lusts and corruptions; but bodily penances and severities are no pleasure to him. Who has required these things at your hands? A few words uttered in assured faith, and with fervent affection for the glory of God, and love to the souls of men, or thirstings after the Lord's image and his favour, form the effectual, fervent prayer of the righteous man, which availeth much. Elijah sought not his own glory, but that of God, for the good of the people. The people are all agreed, convinced, and satisfied; Jehovah, he is the God. Some, we hope, had their hearts turned, but most of them were convinced only, not converted. Blessed are they that have not seen what these saw, yet have believed, and have been wrought upon by it, more than they that saw it.
