Did you forget 1 Corinthians chapters twelve and fourteen?
Where the Corinthians Jews, or gentiles? Part of the 12 or not?
.
My view is this
1 Corinthians was written year before Acts 28, before the Holy Spirit declared the entire nation will be blinded (Acts 28:25-28)
After Acts 28
In the book of Philippians 2, which was written after Acts 28, one the prison epistles,
25 Yet I supposed it necessary to send to you Epaphroditus, my brother, and companion in labour, and fellowsoldier, but your messenger, and he that ministered to my wants.
26 For he longed after you all, and was full of heaviness, because that ye had heard that he had been sick.
27 For indeed he was sick nigh unto death: but God had mercy on him; and not on him only, but on me also, lest I should have sorrow upon sorrow.
28 I sent him therefore the more carefully, that, when ye see him again, ye may rejoice, and that I may be the less sorrowful.
In the book of Timothy, written after Acts 28 and at the end of Paul's life on Earth, he wrote
"Drink no longer water, but use a little wine for thy stomach's sake and thine often infirmities" (1 Tim 5:23)
2 Timothy 4:20
Erastus abode at Corinth: but Trophimus have I left at Miletum sick.
In all these 3 examples, Paul no longer possess the gift of healing, no more healing handkerchiefs.
