“And these signs shall follow them that believe...they shall lay hands on the sick and they shall recover.” Mark 16:17-18
I recently read a piece by Kenneth Copeland concerning healing. He described the frustration he'd experienced when people he'd prayed for weren't healed. One day in prayer the Lord addressed that issue - His answer, “Healing always comes.”
Kenneth was shocked. If that was true why wasn't everyone healed? God then said this.
“'I didn't say they'd all receive it,' He answered. Then He spoke very sternly to me. 'I do my part. And I said they would recover!'”
Kenneth then understood that God didn't hold back. Healing always came but not all would receive it.
Andrew Wommack has some great teachings on healing. On one broadcast he mentioned the unconventional methods Jesus employed. The Lord didn't do these just to cause a spectacle but to force people to use their faith. A good example is found in John 9:1-7. Jesus covered a blind man's eyes with mud. He added another barrier to further impede the man's ability to see. He then instructed the blind man to go to the Pool of Siloam and to wash. In order to comply the man would have to navigate a distance of about three quarters of a mile through the streets of Jerusalem. Twisting and turning, filled with people, animals, shops and so forth this was a virtual obstacle course for someone with sight let alone a blind man. In order to receive his healing the man exercised his faith, made his way to the pool, washed and was healed.
The word recover in this verse indicates a change in one's status, but it is not time sensitive. It does not necessarily mean immediately. Healing may or may not manifest instantaneously, but it always comes. You can read this in Mark 8:24. This blind man's sight wasn't totally restored the first time Jesus prayed for him. Jesus also ran head first into a wall of unbelief which prevented Him from working miracles except He healed a few people, Mark 6:5-6.
If we don't see immediate results when we pray for others or receive prayer ourselves it doesn't mean that nothing happened. As far as God is concerned healing came. As a recipient perhaps we need to exercise our faith and not just try to piggy back off the faith of someone else. Consider it done and then listen for any instructions God may give you. Settle the matter in your heart immediately. Healing always comes. We have God's word on it.
