19 My brethren, if any among you err from the truth, and one convert him; 20 let him know, that he who converteth a sinner from the error of his way shall save a soul from death, and shall cover a multitude of sins.

The last message of the epistle is vitally related to the message which precedes. There we were concerned with bodily healing, but also with the forgiveness of the sins to which the sickness may have been due; here we are encouraged to have a part in the healing of souls; but while in the former case we were concerned with those who felt their need, here we are encouraged to seek for those who may be ignorant of their danger or indifferent to their peril. The case is that of one who has gone astray; he has erred "from the truth," not so much in the matter of belief as of practice. To bring him back again to the right path will "save a soul from death," and "cover a multitude of sins." In such saving work every follower of Christ may be engaged. Surely we shall need to resort anew, as in the cases of physical healing, to the "prayer of faith"; surely there must be in our own religious experiences that reality upon which the epistle everywhere insists; surely, we must seek "the wisdom that is from above" which is "first pure, then peaceable, gentle, easy to be entreated, full of mercy and good fruits, without variance, without hypocrisy."
