This morning a brief discussion took place about how saying "go with your gut," is insulting to the Spirit. If you subscribe to that thought then when people say "gut," just think of it as an acrostic for God Understands This.
Anyway, it made me think more about each of our own intuitions. Like Malcolm Gladwell suggests in his book, Blink: The Power of Thinking Without Thinking, your gut reaction is made up of a history of experiences that in the blink of an eye gives you a pretty good reason for having a gut feeling that is often times more accurate than not.
I would not deny the power of the Spirit in any circumstance, but I am also not willing sacrifice the idea that God gave us a brain and the ability to grow through our personal experiences. If two people have gut reactions that are opposing views, then which one is of the Spirit?
Nonetheless, we may not understand or know why our gut tells us to react one way instead of another, but then again, that's all the more reason to say "God understands this".
