My son Earl is a construction foreman. One day he tumbled from a scaffold, managing to break his fall by grabbing on to parts of the scaffold on the way down. He received only minor scratches. Embarrassed by the fall, he climbed back up to continue working. Then he noticed his co-workers holding up hastily made signs reading, 9.6, 9.8, and 9.4.
Common sense is also a rather basic part of living the Christian life.
He simply asks us to live in a way that is wise. That makes incredible sense, for we know that the only things that result from associating with evil are bad. You hang around bad people, for instance, and bad things will happen. Evil will destroy any godly thing you try to do. Ask God to help you pursue these six items every day for a week.
