According to the Bible, we should all be able to do miracles if we have a modicum of faith. So where are all of these millions of miracles?
Christians have a lot of excuses for why we don't see miracles, and what miracles we do hear about are always suspiciously armored against investigation. The Bible never really explains why that changed, and even promises that it won't.
And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues;
they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.”
