When my boys, were young they enjoyed playing with Transformers. They could transform what looked to be an ordinary car into a robot of destruction at will. After conquering that playful task, they would transform their toy back into a playful simple car. When Jesus told us to be transformed into His image, He did not mean to be as a child’s toy. We are not to bounce back and forth with our desires. We are to die to our old nature.
Romans 12:1-2 (ESV)
1 I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.
2 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.
