could and we would, since this is our privilege,

if preacher and desperate-receiver CLEARLY know
信心不够,是常态,祷告求主帮助就是了
(信心够-(many living examples,they believe 100%
God love them, God is willing to heal them and
God can easily heal them),神不医治也是常态,
看到医治,也不能下定论是信心够了)
this would be a great practice in our everyday church life.

医治, praise Lord!
不医治, praise Lord too, because we believe
He always offered us the best!

Pray for 医治, Nothing wrong.

However,
if we believe
HEALTHY body is the best that God would offer His children
or
WEALTHY life is the best that God would offer His children
as those famous preachers said
that's the problem
