They forget we still have bodies under the fall....our souls have een redeemed but not our bodies. If all they say was true then they should all be in perfect health now. But even the healers were plagued with long term illnesses they kept under wraps until after they died and it was revealed.
God is gracious to take events and happenings and illnesses and use them for His good and purposes....we go thru life and life is difficult..He said it would be so...but along the way HE meets us and with us to see us thru.
As for those who cannot accept your scripture reference....to do so would rob them of the “other” add ons and they just won’t give them up.
As long as we are in these bodies, they are VILE. We are told to put no confidence in the flesh. The outer man is perishing daily. And yet, there are those whose sole purpose is praying for a healing of this vile body? And if He chooses NOT to heal it, then WHAT? WHAT are they left with, if all their hope and faith is in that healing? Certainly this Scripture comes to mind:
Holding faith, and a good conscience; which some having put away concerning faith have made SHIPWRECK:.."1 Tim. 1:19.
If faith can only be in a healing experience, then IF that healing doesn't occur, that faith is made shipwreck. And it has taken all other forms of our faith right down with it. That is a person who is no longer an effective workman for Christ. Who will stand ashamed before Him one day, having lost all because their "faith" was placed in one "proof" that God WOULD, not that God has His own plan.
And even though we are perfect in Him and seated with Him in the heavenly places, we are not perfect yet. The old nature is very much alive, we still all sin, we are still here on earth, not up IN heaven.
The redemption of our souls and bodies is both completed and has not yet been completed.
Easy and pat answers just don't cut it. I've known far too many really mature Christians and very godly people who deal with health issues. They are not healed.
For that matter, the miraculous healings that the faith movement claims, just is NOT there. There is a staggering difference between the healings claimed and reality, and reality just does not line up with their doctrine of how it SHOULD be, or how they would like it to be.
James 1:2-4 2 Count it all joy, my brothers, when you meet trials of various kinds, 3 for you know that the testing of your faith produces steadfastness. 4 And let steadfastness have its full effect, that you may be perfect and complete, lacking in nothing.
