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 the prayer of faith shall save the sick,.... That is, the prayer of the elders, being put up in faith by them, and in which the sick person joins by faith; such a prayer is a means of bringing down from God a blessing on the sick man, and of restoring him to his former health:

and the Lord shall raise him up; from his bed of sickness, on which he is laid, and bring him forth to praise his name, and to fear and glorify him.

And if he have committed sins; not that it is a question whether he has or not, for no man lives without sin, nor the commission of it; but the sense is, if he has been guilty of any sins, which God in particular has taken notice of, and on account of which he has laid his chastising hand upon him, in order to bring him to a sense of them, and to acknowledge them; which is sometimes the case, though not always, at the same time that his bodily health is restored:

they shall be forgiven him; he shall have a discovery, and an application of pardoning grace to him: and indeed the removing the sickness or disease may be called the forgiveness of his sins, which is sometimes the sense of this phrase in Scripture, as in 1 Kings 8:34.
