I just realized why it seems such a foreign concept to me. For background: I'm a non-denominational Christian (I've been in several different churches over the years) currently living in the Southeast US. In my religious circles it wouldn't be at all strange to hear someone say "I feel like God is leading me to do X" or "I've prayed about it and I feel lead to do X" but it's never acceptable (at least in my culture) for someone to tell another person outright
"God told me to tell you that you should do X". I would run the other way from anyone who says something like that. They are either putting themselves in the place of God or claiming to have some special revelation about MY personal situation without me even asking their opinion? No way. I simply can't wrap my mind around why Jessica was so easily drawn in by a man telling her that he was "prompted" to tell her she should come work for him. I agree, tresir2012, that this prompting stuff sounds like a way to get others to do what you want under a cloak of spirituality.
