It's a bit more difficult for grownups, isn't it. The entry and exit of God into and from the world are certainly fraught with difficulty. I find it best to just leave my doubts at the door and do what I'm supposed to do.Of course a ghost knocked you up Mary, happens all the time honey,you say the ghost was dressed as a Roman soldier & stunk of wine!,and now your pregnant. Oh shit!, how gullible is that old man Joseph?, stick to the ghost story, he's not that bright.
God bless you.
ps: I do occasionally ask God to clear some of that stuff up but He just says do more of what I'm supposed to do and less of what I'm not supposed to do, like goofing off on Topix, and call it a day.
