The balance of yin and yang is not the same as the Holiness of God.
Holiness is not harmony, or balance, or yin helping yang. Star Wars made popular the phrase "bring balance to the Force." And now you'll hear people comment, perhaps in a joking manner, about having two diverging, different styles or ideas be present in the same situation as "bringing balance to the universe" (or Universe). But while there is often wisdom in human affairs in seeking a middle way between extremes, if we're attempting to follow Christ there's no inherent virtue in balance, or harmony between two things that are just different. Or goal, our striving, should be for Holiness, to imitate Christ, not just to live according to a compromise among the most popular worldviews in the zeitgeist.
