Have you ever changed your mind? Do you see the ambiguity in this question? It could mean that you have used your existing mind to reach a different opinion on some question, but it could also mean that you have acquired a new mind, which is a much more substantial change. My word refers to putting on the mind of Christ, and to being transformed by the renewing of your mind. These are big changes. Have you experienced them? How would you know? Do you live with a conscious awareness that your view of reality has undergone a radical shift and there is no going back? Then you have really changed your mind.
