We believe in the divine healing of our bodies and souls by the Lord. One of the Old Testament names of God is Jehhovah-Rapha “the Lord that heals you”. This is based on the covenant promise of the Lord to Israel in Exodus.
“If thou wilt diligently hearken to the voice of the Lord they God, and wilt do that with is right in his sigh, and wilt give ear to His commandments, and keep all His statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians; for I am the Lord that healeth thee.” – Exodus 15:26
“Bless the LORD, O my soul: and all that is within me, bless his holy name. Bless the LORD, O my soul, and forget not all his benefits: Who forgiveth all thine iniquities; who healeth all thy diseases;” – Psalms 103:1-3
The Lord healed all manner of sickness and disease while He was among the people (Matthew 4:23-24). He has the same capability today as well (Hebrews 13:8).
Jesus suffering on the cross of Calvary not only paid the price for the healing of our souls, but the healing of our bodies as well. “Who his own self bare our sins in his own body on the tree, that we, being dead unto sin, should live unto righteousness: By Whose Stripes Ye Were Healed” (I Peter 4:24; Isaiah 53:5). “Himself took our infirmities, and bare our sickness” (Matthew 8:17; Isaiah 53:4). The divine healing for our bodies, therefore, is in the atonement.
It is up to God as to whether someone is healed or not. If they are repentant and have faith, this is all that is required (Matthew 8:5-10). Sin and unbelief are a hindrance to healing (Matthew 13:58; Psalms 66:18). God may heal miraculously or by other means, instantaneously or progressively. It is God that is in control of our healing.
Jesus said, “…these signs shall follow them that believe… they shall lay hands on the sick and they shall recover (Mark 16:17a-18b). James wrote in his letter to all the churches: “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: 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. 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.” – James 5:14-16
