They will may mean it did happen in history, as the Gospel spread... as opposed to a continuing blanket promise of some type.
Mark, catch this rattler and see if he be holy!!!!!
RE: They will may mean it did happen in history, as the Gospel spread
If I recall correctly, in the end of the Book of Acts, St. Paul actually had a snake hanging on his hand ( did it bite him?), anyway, he shook it off and did not suffer any ill effects.
THAT was one incident where Mark 16:18 was relevant. Not sure if that is to be made normative for all Christians.
Ha, not a chance. 😁 I have heard of holy rollers before, but never Holy rattlers. I know Paul survived the snake bite, but I wonder who drank the poison? 🤣 I have seen those people on TV, dancing around the room with a bunch of snakes, making fools out of themselves. To me, it almost looks like the kundalini spirit.
