Inspiration and guidance through prayer is a different thing to me than having a conversation and getting answers in such things as "go marry this guy you just met"
I have trouble with someone who would give testimony in church the way she did. It spoke more of vanity than anything else to me. It also was troubling that she believes that she's having conversations with God on such subjects. I wouldn't vote for her because of it, but don't mistake that for me thinking its wrong. I don't. However, i do think it potentially leads to self righteousness and the arrogance of believing you are on some sort of ordained mission from god.
I've learned as i am sure you have that what's said on the campaign trail shouldn't always be taken so seriously. So when a politician talks about inspirational guidance, i don't really listen too much because most of them are in the say anything mode.
Inspiration and guidance through prayer is what Bachmann did/does. It's like the Ron Paul statement I posted (either in this thread or another one) where he said he seeks God's/the Holy Spirit's guidance in everything he does. Hillary said the same thing. If you step back and compare what they have said, it's exactly the same. But I think we'll have to agree to disagree in that regard.
You think her comments show vanity? They actually show humility IMO. What she was saying is she wasn't going to do solely what she wanted, but wanted to follow God's plan for her. That's the antithesis of vanity or selfishness. It's classic Christian-speak. I think that's largely why this doesn't bother me. That's how Christians talk, especially in church.
I do agree with you that you have to take whatever most of these politicians says with a gain of salt. I like Bachmann, but I'm not for an instant saying she isn't like most politicians who say what they need to say to get elected. The only difference here is she engaged in church-speak, in a church, most likely after being invited to do so.
