Luke 13:16 "And ought not this woman, being a daughter of Abraham, whom Satan hath bound, lo, these eighteen years, be loosed from this bond on the Sabbath day?"
Sickness is not a blessing in disguise, God does not withhold healing from us to teach us or show us things. In the same way that all our sins were forgiven at the cross all our sickness was dealt with at the cross.
God in his grace has provided all we need to live in victory. Jesus never refused to heal anyone in scripture and everyone who came and asked to be healed was healed. Jesus never withheld healing.
The full provision of our healing is included in our salvation and we have access to full power of Christ and this power works within us. I have received the fullness of Christ in my spirit and I am united into all God’s complete work, inside me.
Here Andrew Wommack explains that healing is part of our salvation, and we need to receive all God has provided for us.
This sickness was the work of Satan - not the work of God. Jesus said it had bound her - not blessed her - for eighteen years. The teaching that says that sickness is actually a blessing in disguise, because the Lord is working His plan in one's life, is not found in scripture. As Acts says, Jesus "went about doing good, and healing all that were oppressed of the devil," not "oppressed of God."
There are 17 times in the Gospels when Jesus healed all of the sick that were present. There are 47 other times when He healed one or two people at a time.
Nowhere do we find Jesus refusing to heal anyone. Jesus said that He could do nothing of Himself, but only what He saw the Father do. His actions are proof enough that it is always God's will to heal!
Jesus provided for physical healing as well as forgiveness of sins. The very word "save" (Gk.-"sozo") is translated "made whole" in reference to physical healing in Matthew 9:22, Mark 5:34, and Luke 8:48. James says "the prayer of faith shall save (Gk.-"sozo") the sick." Many scriptures mention the healing of our bodies in conjunction with the forgiveness of our sins.
Healing is a part of our salvation, just as much as the forgiveness of our sins.
It is God's will that no one should perish, but many do because of their unbelief. Likewise, it is God's will that we all be healed, but not all are healed because of failure to believe. It is a mistake to assume that whatever God wills will automatically come to pass. We play a part in receiving from God. Believe His Word today.
