(13) Is any among you afflicted? let him pray. Is any merry? let him sing psalms. (14) Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord: (15) And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he has 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 avails 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.

Ephesians 6:16-20 (KJV) (16) Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. (17) And take the helmet of salvation, and the sword of the Spirit, which is the word of God: (18) Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints; (19) And for me, that utterance may be given unto me, that I may open my mouth boldly, to make known the mystery of the gospel, (20) For which I am an ambassador in bonds: that therein I may speak boldly, as I ought to speak.

(16) Rejoice evermore. (17) Pray without ceasing. (18) In everything give thanks: for this is the will of God in Christ Jesus concerning you. (19) Quench not the Spirit. (20) Despise not prophesying(s). (21) Prove all things; hold fast that which is good. (22) Abstain from all appearance of evil. (23) And the very God of peace sanctify you wholly; and I pray God your whole spirit and soul and body be preserved blameless unto the coming of our Lord Jesus Christ. (24) Faithful is he that calls you, who also will do it. (25) Brethren, pray for us.
