According to the "2001 religious survey" by Barry Kosmin, (the biggest survey on US religious faith ever done) this is the faith of most US Christians. But there's the great Steven Weinberg quote "If we use our own moral judgement on which parts of the Bible to follow, aren't we just using our own moral judgement? What do we need the Bible for?" So I'm going to argue that the most people who call themselves Christian aren't really Christian. They've got a wide variety of various faiths we haven't given names to. But they like to share the title Christian, because it gives them the, (false) sense of having something in common.
edit: my point is that if you're not following the Bible literally you can combine Christianity with any activity no matter how bizarre. If you are following the Bible literally you immediately run into the problem of that it isn't compatible with modern moral values. So you'd be arrested if you tried.
This is quite central to Christian beliefs. It's the belief that God works in secret by sneaking around doing good, and trying to fool people into that he doesn't exist...to test our faith. Doing some act miraculous act that would break the laws of nature and prove his existence, would be way to easy. That would convert every human soul in a second. God wouldn't want that would he? It would make everything so boring and predictable. But hey, wait a minute, he's omnipotent.... hm.... yeah.... why is he so unwilling to convert people?
