James 5:17-20

Elias was a man subject to like passions as we are, and he prayed earnestly that it might not rain: and it rained not on the earth by the space of three years and six months. And he prayed again, and the heaven gave rain, and the earth brought forth her fruit. Brethren, if any of you do err from the truth, and one convert him; let him know, that he which converteth the sinner from the error of his way shall save a soul from death, and shall hide a multitude of sins.
