What are some situations documented outside of the Bible in which God intervened in human affairs? As a continuance of whether we can truly know anything about God's affairs and also whether all Christian views need a Biblical basis, I was curious if there were any instances of God's influence on humanity that are not mentioned in the Bible. On a basic level, many people like to believe that God intervenes from time to time in answering prayers; surely all the ones post-Bible aren't documented in the Bible (like, if you had a prayer answered yesterday, obviously it's not in the Bible). I'm looking for something a bit more substantive than small answered prayers though, like God revealing himself to a group of people or something of that nature, which isn't strictly found in the Bible but most/many/some Christians hold the event to be true in the Christian lore.

What are some of the situations accepted by Christians in which God performed some act, or revealed himself, or otherwise influenced mankind in some way that is not mentioned in the Bible (if any)?
It is challenging to get all Christians to believe in anything together; with all the different denominations each has their own particular views of God, of the Trinity, of the validity of each of the various stories in the Bible. Did the flood actually happen? Or is an anecdote, simply there to teach us a lesson? Can a man really live inside of a really big fish? Or was it a whale? Which translation is most accurate?

The learned Christian finds that although all Christian men of faith believe in the same God, they vary in the extent of their beliefs. That said, some particular beliefs may be shared more widely than others; for example, the idea that God is all-powerful, all-knowing, and all-loving is a belief that is probably shared among the great majority of Christians, regardless of denomination. Regarding the question being asked here—whether there is any generally shared belief involving God's intervention in human affairs that is outside Biblical documentation—the simple answer is "No". There is no widely shared belief in any event in which God revealed himself or otherwise intervened in human affairs that is documented outside the Bible. There are some denominations, however, that do profess such beliefs, but they make up a relatively small minority of the Christian whole and as such cannot be taken as representative of the "average" person of Christian faith.
