Matthew Poole and continuators on James 5:15

15 And the prayer of faith shall save the sick, and the Lord shall raise him up , and if he have committed sins they shall be forgiven him .

i. e. Proceeding from Faith; the Cure is ascribed to Prayer, the moral means, and standing Ordinance, not to the Anointing, which was but ceremonial and temporary; and to Faith in Prayer, to shew that this remedy was effectual only, when Faith (requisite to the working of Miracles) was active, viz. in a certain perswasion that the Sick person should be healed.

Restore to Health (if God see it fit, and the Health of the Body be good for the Soul) Mark 10.52. Luke 7.50. and 18.42.

The Elders pray, but the Lord raiseth up, being prayed to in Faith.

The same as saving before, only the Word seems to respect the Sick Man's lying upon his Bed, from which he riseth when he is healed, Mark 1.31.

If he have by his Sins procured his Sickness; or those Sins, for which particularly God visits him with Sickness; Sin being often the cause of Sickness, Matth. 9.2. Iohn 5.14. and 1 Cor. 11.30. though not always, Iohn 9.2.

God will take away the cause as well as the effect; heal the Soul as well as the Body, and Prayer is the means of obtaining both.
