None of those choices fit. It's simply exactly as Christ said.
I've learned personally that what He says works exactly as He says -- that means with the conditions He said. But it is true that very often people are not asking as He said/doing as He said in those conditions, and then how could they expect that outcome He said, when it's not the way He said? (but yes, it seems also God makes allowances depending on things we cannot see) It may be how rarely I prayed, and how I took it so very seriously, that I never prayed for things that seemed as if they would not align to His words. But His words include physical healings. I can testify it's not that you are somehow truly 'perfect' in that heaven-like way by our own human judgement, but it is instead how you learn by listening through the entirely of the gospels, so that you get just what is meant, because you listened all the way through. For example, what does it mean to 'keep' his words. Well, in the Old Testament some helpful instructions were given, to meditate day and night, as you wake up, and as you go to sleep, on his words.
(It might help for me to point this out more often when I tell people to try to truly 'listen' when they read His words. We are not to just try to get something and leave. You want to remain in Him, remain in His Words (John chapter 15))
