It's always been God who does the works. However, He gave authority to some people.
27 If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret. 28 But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God. 29 Let the prophets speak two or three, and let the other judge. 30 If any thing be revealed to another that sitteth by, let the first hold his peace. 31 For ye may all prophesy one by one, that all may learn, and all may be comforted. 32 And
the spirits of the prophets are subject to the prophets. 33 For God is not the author of confusion, but of peace, as in all churches of the saints.

Paul states plainly that the spirits of the prophets are subject to the prophets.
But Peter put them all forth,
and kneeled down,
and prayed;
and turning him to the body said, Tabitha,
arise.
And she opened her eyes:
and when she saw Peter, she sat up.
Peter prayed and she rose up. He didn't tell them to pray and see what happens. It was immediate. That's the gift of healing. He didn't have to wait and hope God answered his prayer. Jesus gave them authority.
18 Verily I say unto you, W
hatsoever ye shall bind on earth shall be bound in heaven: and
whatsoever ye shall loose on earth shall be loosed in heaven. 19 Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven. 20 For where two or three are gathered together in my name, there am I in the midst of them.
