"Maturity is living with the tension." When I learned of the coming retirement of megachurch pastor Rick Warren, I opened his inspiring book "The Purpose Driven Life" to a random page and encountered those words. He was writing about how to manage one's expectations of fellowship at church. "Longing for the ideal while criticizing the real is evidence of immaturity," pastor Warren wrote. "On the other hand, settling for the real without striving for the ideal is complacency."
