It’s more common for Christians to experience miraculous occurrences or prophetic/mystical gifts than to actually be given the gift of working miracles.
However, it’s reasonably common. It’s not even a case of “friend of a friend.” If you hang around Christians, you will hear plenty of first-person accounts of miracles done as a result of prayer by a whole church, by a small group, or by a certain person. If the need is great, it’s often not even a particularly saintly person who is given the gift.
For example, it’s fairly common in groups that feed the poor or the needy, or who do disaster relief, to experience a miraculous multiplication of food or drink. And no, I don’t mean miraculous charitable contributions, or everybody somehow manages to pull together enough. I’m talking straight up “soup pot that does not empty, no matter how many times you put your ladle in there, maybe even for a week without replenishment” kind of stuff. People don’t like to say too much about it when it’s happening, but this kind of stuff does happen; and you can easily hear about it from people who were there. And they’re the kind of people who know exactly how many bowls of soup you can get per soup pot, so it’s not like they’re just dreaming that they ladled out endless gallons.
And then there are people who are just ridiculously saintly and unworldly, and who do miracles without hardly even noticing them. It’s not just a Catholic thing or an Orthodox thing, and it’s not just monks and nuns. They aren’t going on TV and showing off; they just do this stuff.
You get people like Bl. Solanus Casey, who not only prayed for people and got miraculous healings for them and great wisdom that changed their lives, but also got miracles involving ice cream cones. Because, he said, Jesus and Mary like people celebrating with ice cream. (And you know, they probably do. But why doesn’t everybody get miraculous ice cream? Who knows? Maybe in an unfallen world, we all would. Why didn’t Jesus make him a great violinist or give him the gift of tongues, either of which would have made his own life easier? Who knows?)
So yeah, I’m pretty sure there’s probably Christians out there today who can walk on water, and they probably do it on their way to check their mail. While thinking about something else. And while still having plenty of their own problems and sufferings.
