Embracing a new lifestyle requires that you embrace a new set of standards. If you want to develop your athletic prowess, you must learn the norms of being a good athlete. If you want to develop a healthy lifestyle, there are certain standards you need to observe to be successful. This is true in every arena of life and is especially true in our discipleship to Jesus. There are certain truths, principles, perspectives that we need to learn and observe in order to be the people that God designed us to be. That's what the letter of Ephesians is all about.
