I read it, nothing about the miracles being stopped in there.
He does not heal in respect to worship by human hands (will) as if he who performs all things... needed the hand(will) of the clay he is forming Christ in .....needing something from the clay.
If He does not live in temples made after the will of man (hands) then neither does he heal therapeutically by the same .
Interestingly the word worship this one time use in the whole scripture that it is used reflects the healing of God after no man
For as I passed by, and beheld your devotions, I found an altar with this inscription, TO THE UNKNOWN GOD. Whom therefore ye ignorantly worship, him declare I unto you. God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands;Neither is worshipped (therapeuo) with men's hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things; Act 17:23
Strongs lexicon …2323 therapeuo {ther-ap-yoo'-o}
from the same as 2324; TDNT - 3:128,331; v
AV - heal 38, cure 5, worship 1; 44
1) to serve, do service 2) to heal, cure, restore to health
God used miracles in parables to hide the spiritual understanding from the lost.. But being healed temporally is not a product of the gospel as evidence a person has the Holy Spirit only to die later showing a person was under the wrath of God all the days of their lives..
If it was true then the many who have tried to duplicate it (drinking poison) would not be shown as false prophets, that bring false prophecy.That kind of poison (false doctrine) only effects those who go above and beyond that which is s written
And when they were escaped, then they knew that the island was called Melita.And the barbarous people shewed us no little kindness: for they kindled a fire, and received us every one, because of the present rain, and because of the cold.
And when Paul had gathered a bundle of sticks, and laid them on the fire, there came a viper out of the heat, and fastened And when the barbarians saw the venomous beast hang on his hand, they said among themselves, No doubt this man is a murderer, whom, though he hath escaped the sea, yet vengeance suffereth not to live. And he shook off the beast into the fire, and felt no harm. Howbeit they looked when he should have swollen, or fallen down dead suddenly: but after they had looked a great while, and saw no harm come to him, they changed their minds, and said that he was a god.Act 28:1
What they did because they did not mix what they saw with faith (the unseen) is make the apostle into a god in the likeness of man ,causing them to commit blasphemy by having other gods before Christ violating the first commanmnet in doing so.
Poison as a metaphor is used in parables always representing the false gospel coming from false apostles.
