The first and most important step in the process of becoming genuinely authentic is to be once again authenticated by the original designer. This is a part of the divine side of human change. God desires to place within each of us a new heart, a heart that reflects him not only in action, but in desire. The Scriptures speak of this transformation as a metamorphosis. We are literally transformed into new creations, not a different kind of creature, but a different kind of humanity.
