Prayer without ceasing and earnest in devotion to faith in Christ.

James 5:15-20 KJV

[15] And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him. [16] Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much. [17] 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. [18] And he prayed again, and the heaven gave rain, and the earth brought forth her fruit. [19] Brethren, if any of you do err from the truth, and one convert him; [20] 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.
