Thank you. No, but I've been following her story pretty close for several years. We'd had some pretty meaningful, if brief, exchanges. For what God has called me to, I don't find it appropriate to pray for every person and their Auntie who requests it online, but I felt right praying for her. God seemed to both give me just the right words for her, and a vision of presumably her final moments, months ago.
I respect that you must follow your conscience, but I know my God and what He has taught me. If you can't receive it, you can't receive it; it isn't my job to convince you. I don't want to get into it, at least not today. The friend I mentioned on Twitter just died, just like I expected she would (God showed me something when I prayed for her months ago). Good for her, bad for us. Probably wasn't a coincidence she came up in conversation today of all days (only time she ever has), though I don't totally understand the how.
I am not personally familiar with any of these teachers, though I have certainly heard of them, usually in a negative light.
Healing is never determined by faith alone, but by what God is doing. Paul wasn't lacking in faith, but God declined his request for healing three times, saying "My grace is sufficient." Otherwise, why do all people physically die (except Elijah and possibly Enoch)?
Actually I have myself meaningfully refuted this doctrine on Twitter when a Christian lady I follow with some notoriety came down with cancer and was being subjected to such judgmental claims of 'your faith just isn't enough.' I don't think I convinced any of them, but she herself was thankful for my comments.
What God has shown me, though, is that our mindset does influence our outcomes and our health, but it isn't a 'name it and claim it' doctrine. It's more about trusting God. For example, I virtually always get sick in the springtime, but this year it would be virtual imprisonment to get so much as a cold. While a specific blessing on my health was spoken, I have been resting in knowing that God's provision for this year includes health to do what is needed, and amazingly I haven't gotten sick even when multiple things that normally get my immune system down were in play.
There is a lot more to it on health than this example shows, but I'm not sure my words or understanding can do it justice. I am much more familiar with how it works on other things. An example would be how in sports they tell you that you have to visualize it first. What they may not understand, though, is that there is a spiritual component to this. For me, commanding something to happen that can happen, but which is difficult to get to, is something I'm much more familiar with. An example would be putting an earring through the piercing hole. This doesn't seem to work as well for my roommate though, probably due to differences in what God has made us each to be.
