the BIBLE is a book that was written by man , but INSPIRED by GOD...which means that GOD came to people in visions and such, and told them what to write...the books of Corinthians were letters from one of the disciples to a people called "Corinthians" so not everything is just "GOD told me to tell this story" some things are inspired by GOD, but from the heart, to other people...but you're right, it IS about belief...anything you believe, you have to have faith in...whether it be evolution or the BIBLE, because "faith is the belief in things unseen"...nobody really knows how everything that Is, came to be...but you choose to have faith in either man, who is in the same position as you, and whom you can see, or a GOD, that is all-powerful and all-knowing

it is still against GOD's word for women to dress like men and men to dress like women, can't remember where but it IS in the BIBLE though...and like ThaQ said, no sin is greater than the other...so basically unless you have NO sins to be forgiven of, do not bring up another person's sin
pray for yourself and pray for them
