First, “is anyone afflicted?” This word means “troubled,” referring especially to persecution or deprivation. For such a person, the admonition is: “Let him pray.” Assuming that he is right with God, and is praying in His will (I John 5:14-15), he can expect either the needed relief or the needed grace.
I John 5:14-15 - And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us: 15. And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
Secondly: “Is any sick?” Here the Greek word actually refers to physical illness. However, the context shows that this particular sickness has come specifically “since (the true connotation of ‘if’) he have committed sins.” The remedy is for such a person to call for the church elders (not the reverse), and “let them pray” (after he has first openly confessed and repented of his sins) in faith, anointing him with oil. Then the promise is that, if the elders themselves have faith and are right with God, the Lord will forgive his sins and raise him up.
Furthermore, their prayer of faith will “save the sick.” The Greek word in this case means “wearied,” rather than “ill,” and it tells us that the sinner has been delivered from the heavy burden of guilt which had wearied his soul, as well as the illness which had weakened his body. There are other reasons for illness besides unrepented sin, but this is a wonderful promise of both spiritual and physical healing when sin is the problem.
