Balance may be the delicate art form practiced by a good gymnast as she bounces across the balance beam or balance could be considered the ability to maintain order in a hectic world. Balance in the human body is the result of the sense of hearing working at it's peak.
What about spiritual balance? A little harder to measure. We'd be tempted to say that spiritual balance is only present when all is going well, but that just wouldn't be true!
Isn't it the Psalmist who writes, destroy them Oh Lord, then with the next breath, forgive me Lord and create a clean heart in me. I guess it's who we turn to most in our time of need that determines whether we are in balance with God or not.
