Many Christians will be familiar with Romans 12:2 "Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is—his good, pleasing and perfect will."
While we most likely have heard that the "pattern of this world" is the sinful world in which we live, there may be more of a personal pattern that we need to replace with a new, transformed mind.
