And should we expect consistency? Look at your own life and theology. I'll bet there isn't a whole lot of consistency there! I know that I catch myself in inconsistencies all the time. Humanity is not a rational being, despite what we would like to think. My goal is to prayerfully eliminate the inconsistencies, though; I want my life to be consistently Christian, with Jesus shining through in thoughts, words, and deeds.
What about you? Is that your goal too?
