Modern Christians, especially those in the Western world, have generally been found wanting in the area of holiness of body. Gluttony and laziness, for example, were regarded by earlier Christians as sin. Today we may look on these as weaknesses of the will but certainly not sin. We even joke about our overeating and other indulgences instead of crying out to God in confession and repentance.
