I'm just trying to explain how I look at healing today and how I understand the scripture you have pointed out. I don't think it's clear enough to just say healing has ended just because of that scripture. Ok, Tim didn't have just a tummy ache, he had more wrong with him, but he may have not needed any prayer for his healing anymore than a child that falls and skins their knee needs prayer. I'm questioning why he wasn't prayed for if it was serious. Could there possibly be another reason why the wine was suggested?
Perhaps I'm using the wrong wording to explain my thoughts about healing today. You understand the term Prayer Ministry...right? Some people have a prayer ministry. These people pray for people to be healed. Pretty simple, but that is what a healing ministry does in my neck of the woods. Yes, people may lay hands on them and pray but normally there is no instant healing involved. If there is, there was a reason for it. Sometimes they heal and sometimes they don't...but it's still a healing ministry. I'm talking about what I believe and understand...not the TV preachers style of healing.
Christians are supposed to be people of Hope. Putting our Hope in Jesus is the most important thing we can do. We also put our Hope in what He is doing and what He will do in our lives ...and yes, sometimes people do not heal because God has a purpose for them to be that way. We don't have to understand it, we just have to know that God always has a believer's best at heart....even if life is hard. We learn to find joy in the midst of all of it. And as we endure to the end, our eyes stay focused on Jesus, in the hope of Him molding us into the vessel He wants.
Now as far as people who claim they have a healing gift. I don't know, because I personally would feel uneasy to announce I had a gift...but that's me. I guess if I had success after success, I guess I would then think God gave me a special gift to share. I guess it would be no different than a child prodigy who grows up with a major talent to play an instrument and they say God gifted them in this area. I guess I'm just too afraid to discount the possibility, because anything is possible with God. I pray that God gives us enough discernment and common sense to tell the difference.
You say if their gift was so powerful, why can't they clear out hospitals...well, I wonder that too at times. If scripture says that it only takes a mustard seed size amount of faith to move mountains, then it must mean their faith is very small and they can only help people in small ways. After all I never read that any of the disciples tried to move a mountain after being told that. I think I would have tried, don't you. :)
I know I have prayed for my car to not stop dead and leave me strained..twice. And both times my car rolled for miles into a gas station....different stations...different cars. I didn't start a Car Rolling Ministry because of that, but I believe in prayer...and I believe God is good...and good to us.
