Renewing of your mind
There is a powerful promise in 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" (NIV). Check out the phrase, 'transformed by the renewing of your mind.' The Bible is literally saying that God can renew your mind.
This article (from a non-christian source) is saying that renewing your mind is actually possible. Of course, we know the real secret to renewal. It's found in the power of God to do a supernatural work within us. I found this an interesting read. What do you think?
