In Jeopardy style, the answer is, “Nature abhors a vacuum.” And the question is, “Why doesn’t fasting make a lasting difference in most people’s spiritual life?”
During the 40 days of Lent, it is a tradition to give up something for the season. Sometimes it is a food item we enjoy, but blame for our weight problem, so we claim to give up chocolate, or pie, or cake as a spiritual discipline, when we really want to lose weight. At times we try to use Lent to work on breaking a bad habit by pledging to give up something like swearing, cigarettes, or road rage for the season, in the hope it will last beyond the few weeks of Lent. But the reality is it doesn’t really work! Usually we are back to our familiar behaviors well before the Lenten season is complete. Why? Because our spiritual life, like nature, abhors a vacuum!
