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.

14. let him call for the elders—not some one of the elders, as Roman Catholics interpret it, to justify their usage in extreme unction. The prayers of the elders over the sick would be much the same as though the whole Church which they represent should pray [Bengel].

anointing him with oil—The usage which Christ committed to His apostles was afterwards continued with laying on of hands, as a token of the highest faculty of medicine in the Church, just as we find in 1Co 6:2 the Church's highest judicial function. Now that the miraculous gift of healing has been withdrawn for the most part, to use the sign where the reality is wanting would be unmeaning superstition. Compare other apostolic usages now discontinued rightly, 1Co 11:4-15; 16:20. "Let them use oil who can by their prayers obtain recovery for the sick: let those who cannot do this, abstain from using the empty sign" [Whitaker]. Romish extreme unction is administered to those whose life is despaired of, to heal the soul, whereas James' unction was to heal the body. Cardinal Cajetan [Commentary] admits that James cannot refer to extreme unction. Oil in the East, and especially among the Jews (see the Talmud, Jerusalem and Babylon), was much used as a curative agent. It was also a sign of the divine grace. Hence it was an appropriate sign in performing miraculous cures.

in the name of the Lord—by whom alone the miracle was performed: men were but the instruments.
