Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect. Romans 12:2 (ESV)
The key method Paul underscores as the means to the transformed life is by the “renewal of the mind.” This means nothing more and nothing less than education. Serious education. In-depth education. Disciplined education in the things of God. It calls for a mastery of the Word of God. We need to be people whose lives have changed because our minds have changed.
