For the record, I'm not saying that God does not heal. I firmly believe He does; however, I believe true healings are under-the-radar and done in privacy (as Jesus stated). Not blasted out over the internet in forums, YouTube videos, and social media by those who were supposedly the "instrument" used for the healing.
And, I believe you are wrong. Based on what most of the church believes and teaches, I would have never even known that God could heal people through my touch or over the phone. I wouldn't have even considered it. I though all healing evangelists were frauds who wanted your money.
But, if it wasn't for someone who used to be a Baptist pastor before God started doing the supernatural through him, I would have never laid hands on anyone. If it wasn't for many along the way who God used to teach me, despite the persecution they suffered at the hands of people who claimed to be believers in Christ, I certainly wouldn't be praying and expecting like I do today.
As an introvert, I certainly didn't want to approach people in Walmart to pray for them, nor ruffle feathers in church by offering to pray for people. But, God wanted me to anyway. And, I only give my name when people ask and then as little as I can, because contrary to your charge, it isn't about me. It is about the One I work for and with.
Even the opportunities that I have had that opened the door for recent phone prayers are because I was willing to share what God had already done through phone prayers. When that person I spoke about gets healed, it will be because he read a post. Had I never posted online, he wouldn't even have this opportunity to be healed. And, he has had this condition for over 30 years, according to his testimony; so I doubt that he had other options banging down his door. And, most doctors would tell him that he is stuck with the ringing in his ears and hearing loss.
Jesus said "these signs would follow", so how do you suppose they serve as signs, if they are done in privacy and under-the-radar. People flocked to Jesus because of what He did. How is that "under the radar". Read Acts. How is that stuff under the radar? Peter walking by and they get healed in the street. God operating only under the radar? Really? That may sound humble, but it ain't Scripturally backed.
I have routinely refused to ask people to provide proof of healing for those on this community that wanted some proof to examine. This time, I felt led to state something before it happened, so when it happened, maybe it would help someone to know that if you just believe and don't doubt what God says, s/he, too, can watch it come to pass.
Certainly, there is time to grow involved. But, we should all be doing this. I'm not special. The problem is that most would rather cut down (so they can feel comfortable in their lack of experience) rather than rise up, because they aren't sure about what they really believe.
