promise about physical healing from disease, like these verses about joy:
这些事我已经对你们说了，是要叫我的喜乐存在你们心里，并叫你们的喜乐可以满足。
向来你们没有奉我的名求甚么，如今你们求就必得著，叫你们的喜乐可以满足。
actual words from Christ Himself.

if you are in Christ, you shall have joy and peace; but where does it say in the bible, that if you are in Christ, you shall have physical healing? if it did, Paul would be the first to prove such promises defunct. where in the bible does it say: if you have faith in the healers, you will be healed? where in the bible does it say: if you don't have faith, you won't be healed?

yet this is what the modern healers tell, or at least imply to their followers. in fact, what's the premises of their so-called revivals? physical healing. why do so many people join their so-called revival? physical healing. how do they get so famous and so controversial? physical healing.

you can lie to yourselves all you want. the fact doesn't change. they built their fame on physical healing. and the plenty of followers follow them because of physical healing. it doesn't matter if Christ is left out or not. the main focus has always been on physical healing, Christ is only a side dish for them.
