You know, that new covenant included a clause wherein God would "put [His] laws in their mind, and in their hearts [He] shall write them."
We're not bound by the contents of the bible. It's okay to graduate, move on, taking what is useful and leaving what is not. If you keep confining yourself to the pages of a book and the mentality of Religion, Inc you're not leaving any room for God to write anything in your heart.
