Now everything you say makes sense - you believe using logic and reason is a sin.
Not a sin per se'...But it is useless when trying to understand the things of God...Or most things for that matter...
It's like having a book telling you every thing you need to know about a topic...So instead of reading the instructions, you close the book and engage your little brain...
Logic and reason are for people who don't 'know' something...It's nothing more than a guess and of course every one thinks their guess is better than the other guy's...And then brag about their brilliance...
If you've got the book, can your simple logic and learn some facts...
