interesting

So I had this interesting conversation with someone today about the mind and heart. She says that you shouldn't make decisions based on your emotions but that you need to make logical decisions based on what your mind is saying. But aren't we supposed to live out of our hearts and listen to our emotions. I just think there is a balance between the two but what is it. I think as Christians we should be passionate people who are living out the truth of God but that doesn't mean squelching our heart. Don't we need to listen to our heart to know what God is calling us to? I don't know the conversation I had made me do a lot of thinking especially about what it means to live a life that is a balance between our hearts and minds.
