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.
16. The oldest authorities read, "Confess, THEREFORE," &c. Not only in the particular case of sickness, but universally confess.
faults—your falls and offenses, in relation to one another. The word is not the same as sins. Mt 5:23, 24; Lu 17:4, illustrate the precept here.
one to another—not to the priest, as Rome insists. The Church of England recommends in certain cases. Rome compels confession in all cases. Confession is desirable in the case of (1) wrong done to a neighbor; (2) when under a troubled conscience we ask counsel of a godly minister or friend as to how we may obtain God's forgiveness and strength to sin no more, or when we desire their intercessory prayers for us ("Pray for one another"): "Confession may be made to anyone who can pray" [Bengel]; (3) open confession of sin before the Church and the world, in token of penitence. Not auricular confession.
that ye may be healed—of your bodily sicknesses. Also that, if your sickness be the punishment of sin, the latter being forgiven on intercessory prayer, "ye may be healed" of the former. Also, that ye may be healed spiritually.
effectual—intense and fervent, not "wavering" (Jas 1:6), [Beza]. "When energized" by the Spirit, as those were who performed miracles [Hammond]. This suits the collocation of the Greek words and the sense well. A righteous man's prayer is always heard generally, but his particular request for the healing of another was then likely to be granted when he was one possessing a special charism of the Spirit. Alford translates, "Availeth much in its working." The "righteous" is one himself careful to avoid "faults," and showing his faith by works (Jas 2:24).
