I was dramatically underweight as a child and young adult. Rail-thin, I was good only for cross country when it came to sports. After college I bulked up, and for about ten minutes I was in fantastically good shape. Now I carry an extra 20lbs or more and have for years.
How easy, in the spiritual life, to be an unrepentant bastard for a good part of life, and then for 10 minutes be “good”, before becoming a self-righteous prig. From prodigal son to elder brother. Ahh, the challenge of the spiritual life.
