He himself took our infirmities and bore our sicknesses.
The bible gives a clear picture of Abraham in Romans 4:20, 21. He staggered not at the promise of God through unbelief; but was strong in faith, giving glory to God; and being fully persuaded that, what He had promised, He was able also to perform. God had established a covenant with Abraham. God in that covenant had spoken to him and made clear what it included, therefore, because of his faith God imputed to him righteousness. We have the right to believe God for healing. I believe the word teaches us that it is His will to heal us and to forgive us of our sins. If we are fully persuaded that it is His will; we know that if we ask anything, according to His will, He will hear us.
I know for many this is like old hat. You might say to me that you do not need to be told this. Yet I believe that it is important to review and affirm what we believe. What is God's will concerning healing in the church age? Is healing still available today? Is healing included in the atonement? Is it God's will to heal us every time? Why is it that some do not receive their healing? It seems to me that healing can be quite a messy business with the possibility of a lot of hurt and misunderstanding. Therefore, many churches have a cessationist attiude that is no longer for today. Years before the coming messiah, Isaiah said surely He has borne our grief (sicknesses) and carried our sorrows (pain). In Isaiah's prophecy in the 53rd chapter it gives us an intimate look about the coming life and ministry of the messiah. It says of Him that He would go on behalf of God's people and through his atoning work purchase salvation and healing. Verse 4 says he has borne our griefs. The word grief there means sicknesses, weaknesses, and diseases. The next verse says that by his stripes we are healed. This includes emotional and physical healing. Verse 10 declares He has put Him to grief. The word grief there implies made Him sick. If that is true Christ sacrificed, purchased our salvation and healing. There was no separation between healing and forgiveness. They were equal. His disciples were so convinced of it that Peter refers to it in the past tense. He believed it was already accomplished.
Even though atonement for our sins is accomplished, we still deal with sin. Though the atonement was perfect we still deal with sickness. When I sin, I do not say it must be God's will that I continue in sin. I do what the apostle Paul says. I press towards the mark, the high calling in Jesus Christ. I am not perfect in my salvation. I do not get under condemnation. I simply keep pressing forward in regards to the truth of healing. If our healing is not manifested right away, I do not say it must be God's will for me to be sick. As Abraham was, I am fully convinced in my heart that God has no other will, but His will revealed in scripture. Let us all be faithful in the word and praying for one another in the word. By His stripes you were healed and if you were healed you are healed.
