"Why does the idea of gifts bother some so much that they go to such lengths to deny it?"
If it were not true, valid, and available to His Own today the adversary would not attempt to mislead people to believe it ended and He is not the same, yesterday, today and forever.
Many of us received in the outpouring in the 70's and have stayed to course.
So often discussion of the divine prayer language we are commanded and encouraged to begin with practice is immediately perverted into the public gift, this misses the mark.
We start with a little and if we get that right He gives more, Jesus first recorded miracle was turning water into wine, He grew later to raising Lazarus. The 12 were given the same as He and most grew, Peter grew to where in Acts we learn the people knew if they lay their sick along the path he took to the synagogue.
Judas received the same as the rest yet he choose to be a devil and deny the power Jesus offers His own.
We see that here, today, now, in these threads that deny the gifts and rail against His truth and His gifts, and often as we see here, they misuse His words to deny, just as the devil did to eve in the garden, "did He really say do not eat of the tree?"
