5:12-18 The sin of swearing is condemned; but how many make light of common profane swearing! Such swearing expressly throws contempt upon God's name and authority. This sin brings neither gain, nor pleasure, nor reputation, but is showing enmity to God without occasion and without advantage It shows a man to be an enemy to God, however he pretends to call himself by his name, or sometimes joins in acts of worship. But the Lord will not hold him guiltless that taketh his name in vain. In a day of affliction nothing is more seasonable than prayer. The spirit is then most humble, and the heart is broken and tender. It is necessary to exercise faith and hope under afflictions; and prayer is the appointed means for obtaining and increasing these graces. Observe, that the saving of the sick is not ascribed to the anointing with oil, but to prayer. In a time of sickness it is not cold and formal prayer that is effectual, but the prayer of faith. The great thing we should beg of God for ourselves and others in the time of sickness is, the pardon of sin. Let nothing be done to encourage any to delay, under the mistaken fancy that a confession, a prayer, a minister's absolution and exhortation, or the sacrament, will set all right at last, where the duties of a godly life have been disregarded. To acknowledge our faults to each other, will tend greatly to peace and brotherly love. And when a righteous person, a true believer, justified in Christ, and by his grace walking before God in holy obedience, presents an effectual fervent prayer, wrought in his heart by the power of the Holy Spirit, raising holy affections and believing expectations and so leading earnestly to plead the promises of God at his mercy-seat, it avails much. The power of prayer is proved from the history of Elijah. In prayer we must not look to the merit of man, but to the grace of God. It is not enough to say a prayer, but we must pray in prayer. Thoughts must be fixed, desires must be firm and ardent, and graces exercised. This instance of the power of prayer, encourages every Christian to be earnest in prayer. God never says to any of the seed of Jacob, Seek my face in vain. Where there may not be so much of miracle in God's answering our prayers, yet there may be as much of grace.And he prayed again - The allusion here seems to be to 1 Kings 18:42, 1 Kings 18:45, though it is not expressly said there that he prayed. Perhaps it might be fairly gathered from the narrative that he did pray, or at least that would be the presumption, for he put himself into a natural attitude of prayer. "He cast himself down upon the earth, and put his face between his knees," 1 Kings 18:42. In such circumstances, it is to be fairly presumed that such a man would pray; but it is remarkable that it is not expressly mentioned, and quite as remarkable that James should have made his argument turn on a thing which is not expressly mentioned, but which seems to have been a matter of inference. It seems probable to me, therefore, that there was some tradition on which he relied, or that it was a common interpretation of the passage in 1 Kings, that Elijah prayed earnestly, and that this was generally believed by those to whom the apostle wrote. Of the fact that Elijah was a man of prayer, no one could doubt; and in these circumstances the tradition and common belief were sufficient to justify the argument which is employed here.

And the heaven gave rain - The clouds gave rain. "The heaven was black with clouds and wind, and there was a great rain," 1 Kings 18:45.

And the earth brought forth her fruit - The famine ceased, and the land again became productive. The case referred to here was indeed a miracle, but it was a case of the power of prayer, and therefore to the point. If God would work a miracle in answer to prayer, it is reasonable to presume that he will bestow upon us the blessings which we need in the same way.

her fruit—her usual and due fruit, heretofore withheld on account of sin. Three and a half years is the time also that the two witnesses prophesy who "have power to shut and open heaven that it rain not."

And he prayed again; after the destroying the prophets of Baal. Baal-worship especially gave occasion to his former prayer, which he puts up out of his zeal to God’s glory, then laid low by the Israelites’ idolatry, and a desire to have them by some exemplary punishment for their sin awakened to repentance. And the destruction of the idolaters, and reformation of the people, who now acknowledged the Lord to be God, might give occasion to this.

And the heaven gave rain; i.e. the air or clouds, which had not been for three years before.

And he prayed again,.... 1 Kings 18:42. Here also is no express mention of his prayer, but it may be concluded from his gestures; and so the Jewish interpreters understand these words, "Elijah went up to the top of Carmel", "to pray, and he cast himself down upon the earth", , "to pray for rain; and he put his face between his knees", "and prayed, and said to his servant, go up now, look toward the sea"; and this he said while he was "in his prayers" (i): and the effect of this his prayer was,

and the heaven gave rain; see 1 Kings 18:45.

And the earth brought forth her fruit: which for the years past it had not; hence there was a sore famine in the land, 1 Kings 18:2. Now the apostle chose to give this example, because it was a common thing for the Jews to ask for rain: we often read of such a doctor, that he prayed for rain, and it came; and of another, that he asked for the rains, and they descended (k): and his view is to observe, that the weakness and infirmities of the saints ought not to discourage them from prayer; and that they should be earnest and fervent in it, as was Elias, a man of like passions with themselves.
