15 And the prayer [that is] of faith will save him who is sick, and the Lord will restore him; and if he has committed sins, he will be forgiven.
16 Confess to one another therefore your faults (your slips, your false steps, your offenses, your sins) and pray [also] for one another, that you may be healed and restored [to a spiritual tone of mind and heart]. The earnest (heartfelt, continued) prayer of a righteous man makes tremendous power available [dynamic in its working].
17 Elijah was a human being with a nature such as we have [with feelings, affections, and a constitution like ours]; and he prayed earnestly for it not to rain, and no rain fell on the earth for three years and six months. [I Kings 17:1.]
18 And [then] he prayed again and the heavens supplied rain and the land produced its crops [as usual]. [I Kings 18:42-45.]
19 [My] brethren, if anyone among you strays from the Truth and falls into error and another [person] brings him back [to God],
20 Let the [latter] one be sure that whoever turns a sinner from his evil course will save [that one's] soul from death and will cover a multitude of sins [procure the pardon of the many sins committed by the convert].
