Well just today I was reading the book of the prophet Jeremiah and in it, God says that He will send Jesus at a certain time in history. He did just that. There are many many many other examples, but that's the main one.
And how many messiahs did your god send at them time? According to history it was a great many and all were contradictory. Perhaps Jesus just won out in the contemporaneous religon religion forum of the time from the many possibilities and therefore satisfied that prophecy post hoc (at least in your mind).
I choose not to comment on prophecies that have supposedly come to fruition at the right time, when they have happened in the past.
Because I can say just about anything I want, I can put in a book that The shuttle will be destroyed and make it look like a prophecy from the past, and make all the conditions of that prophecy look like I called them out before the event, and it just happened to happen at the right time.
But, you take it on faith that someone did not do that to the book of Jeremiah, you take it on faith, that God indeed told him about the future and the circumstances relating to Jesus' coming.
