Verse explainer
Mutual confession between believers — not a confessional booth — and the prayer that follows it carries remarkable power.
Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
BSBTherefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man has great power to prevail.
The plain meaning
James 5:16 sits at the end of a passage about sickness, elders, and prayer (vv. 14-15). After urging the sick to call for elders to pray over them, James widens the circle: all believers are to confess to one another and intercede for one another. The Greek word for 'faults' here (paraptōma) covers offenses and slips, especially those committed against one another — the kind of thing that strains relationships and weighs on a conscience. The remedy is mutual, horizontal: you confess to the person you've wronged, or to a trusted fellow believer, and you pray for each other. The second half of the verse stands on its own: the prayer of a righteous person — not sinless, but sincere, justified, and genuine — carries great weight with God. The Greek phrase rendered 'effectual fervent' describes prayer that is energetic, earnest, and alive, not perfunctory or rote. James closes the chapter with Elijah as the proof: an ordinary man whose fervent prayer shut and opened the heavens (vv. 17-18).
The common misreading
What the commentators say
Clarke insists the text gives no support to auricular confession to a priest: members confess to each other, and the priest would be just as obligated to confess to the laity as the reverse. The social confession he endorses is horizontal and mutual — it humbles the soul, keeps self-applause in check, and drives the penitent to watchfulness and prayer. The 'effectual fervent' phrase, he notes, describes prayer wrought in the soul by a divine energy — a spirit of supplication poured out when God is about to act.
Gill draws the same contrast with Rome: the confession James requires is of sins committed against one another, made by the offending party to the offended for reconciliation — a plain, practical purpose. The prayer that prevails, he adds, is not any person's prayer but a righteous man's earnest, Spirit-wrought intercession. He reads 'effectual fervent' as prayer that is 'inwrought' — not composed from a book but pressed into the heart by the Spirit — and therefore sure to be heard and answered.
JFB notes that the oldest manuscripts read 'confess therefore,' connecting the command to the preceding sick-room scene and then broadening it to all believers. They distinguish three legitimate forms of confession: to a wronged neighbor, privately to a godly minister when seeking counsel or intercessory prayer, and open penitential confession before the church. On 'effectual fervent,' they favor the reading 'energized by the Spirit' — the righteous man's prayer avails much precisely because the Spirit animates it.
The word behind it
'Being energized' or 'working effectively.' From the root energeō, the source of the English 'energy.' It modifies the noun 'prayer' (deēsis) and describes a supplication that is active, alive, and forceful — as opposed to mechanical or routine recitation. The phrase 'effectual fervent prayer' in KJV translates just this one word plus 'deēsis.' The point is not the volume or length of the prayer, but the living quality of engagement behind it — what Clarke calls prayer 'suggested and wrought by Divine energy.'
