If faith speaks to the heart and reason speaks to the mind which one is telling the truth?

if you're a believer, all you have to do is ask and you will receive. you seem to phrase this question as though either the heart OR the mind is involved. i think both are involved and both are right UNLESS they're clashing. if you've read the bible, you should know what is right in that case. and even if you don't then... well, i always ask Jesus.
