It is not surprising to find that James dealt with sickness (Gr. asthenai, weakness) in this epistle. He referred to the fact that departure from the will of God sets the Christian on a course that, unless corrected, may result in his or her premature physical death ( James 1:15; James 1:21; James 5:20). Spiritual weakness, and sometimes physical sickness, result from sinful living. James gave instructions about how to deal with these maladies in James 5:14-20. [source][source][source]
