Proof is easy to find, we can go drag someone out of a hpospital emergency room right now.
And that is my point, if these people had the genuine Holy Spirit gift of healing, they would not be holding meetings, they would be in Emergency rooms and hospices.
I always wondered about that. If I was given divine healing powers, I'd hang out where there were a lot of injured people, such as an emergency room, rather than trying to make money in faith healing meetings.
By that logic, ministers and preachers should be in the bars and strip clubs, in the divorce courts and opium dens. You know, I mean, if God is able to actually SAVE someone nowadays. If it's just happening in the churches, and offerings are being taken, then salvation today is phony, just a bunch of emotional shamaanism.
I'm just trying for consistency here...
What about Jesus? As God, He had the ability to heal everyone. But He didn't. Reading through the gospels, you'll see that the faith of the healed was a critical factor. God invites each of us into a relationship with Him. He wants us to come of our own free will.
The healing gift is not a magic wand. We don't get to pick and choose who will be healed. Only God can heal. We are sometimes privileged to have Him work through us that we might partner in His divine plan -- and that plan is to see people come to Him. If God chooses to heal, it is because He is a merciful God, and because He most of all desires people to come into relationship with Him. The afflictions of this world are temporary, but separation from God is eternal.
Think of it this way: If I had a healing gift, and went to the emergency room, and everyone I prayed for was healed, what would be the outcome?
Would everyone come to Christ? No. Those who don't want to believe would explain it away.
The key to all of this is that people must come to Christ of their own free will.
