You start attacking anybody else who is not like you. If you don’t know how to deal with exceptions, surprise and spontaneity by the time you’re my age, you become a predictable series of responses of paranoia, blame and defensiveness. (Richard Rohr)
Work at getting along with each other and with God. Otherwise you'll never get so much as a glimpse of God. Make sure no one gets left out of God's generosity. Keep a sharp eye out for weeds of bitter discontent. A thistle or two gone to seed can ruin a whole garden in no time. Watch out for the Esau syndrome: trading away God's lifelong gift in order to satisfy a short-term appetite. You well know how Esau later regretted that impulsive act and wanted God's blessing—but by then it was too late, tears or no tears.
