James 5:16 Confess your faults one to another, and pray one for another, that you may be healed. The effectual fervent prayer of a righteous man avail much.
There is a twofold secret of bodily healing: Confess your faults one to another – admit what you have done wrong; Pray one for another, that you may be healed (Mat. 21:22; Mar. 11:24). The Greek word for faults is paraptoma which means a falling aside when one should have stood upright; a transgression; a moral fall.
A couple of Biblical facts about Sickness and Healing: Both death and sickness originated with sin and are now being propagated by satan (Job 2:6-7; Luke 13:16; John 10:10; Acts 10:38; Rom. 5:12-21). The first prophecy and promise of redemption included healing (Isa. 53:5; Mat. 8:16-17; 1Pet. 2:24). Healing was promised on condition of obedience (Psa. 91:1-16; Isa. 58:1-14; Jas. 5:14-15). God permits (allows ) satan to afflict sinners and even His own people when they go astray, to bring them to repentance (Job 33:12-30; Psa. 38:1-22; 103:3; 1Cor. 5:1-5; 2Cor. 2:6-11). Health, as well as healing, was promised when men met certain conditions (Pro. 3:1-8; 12:18; 18:21; Isa. 58:1-14; 1Pet. 3:10-11; 3Jn. 1:2). Christ came to redeem from both sin and sickness (Isa. 53:1-12; 61:1-2; Mat. 8:17; 1Jn. 3:8). The Holy Spirit was sent into the world to carry on the healing ministry (Acts 2:33; 1Cor. 12:9; Heb. 2:3-4). Healing is provided as part of Christ’s atonement (Isa. 53:4-5; Mat. 13:14-15; John 3:14; 10:10; Rom. 8:11; 1Cor. 11:23-32). Healing is on the same basis as forgiveness of sins – prayer and faith (Mat. 9:1-7; 13:15; 21:22; Acts 28:27; Jas. 1:4-8; 5:14-16; Heb. 11:6). God has provided all necessary means of healing and complete defeat of satanic powers (2Cor. 10:4-5; Eph. 6:10-18; John 14:12-15; Jas. 4:7; 5:14-16; 1Pet. 2:24; 5:7-9, 18). Healing is always the will of God for His people who may: “ask what ye will” (John 15:7); “whatsoever” (Mat. 21:22; John 14:12-15; 15:16); “anything” (John 14:14); “what things soever you desire” (Mar. 11:22-24); and “much more” than earthly parents would or could give their children (Mat. 7:7-11).
Thus, it is clear in Scripture that physical healing is provided for in the Old and New Testaments. The New Testament is based upon better promises than the Old Testament (Heb. 8:6).
