“Pampered bodies grow sluggish through sloth; not work but movement and their own weight exhausts them. Prosperity unbruised cannot endure a single blow, but a man who has been at a constant feud with misfortunes acquires skin calloused by suffering; he yields to no evil and even if he stumbles carries the fight on upon his knee.” (Seneca)

Those who struggle are stronger than those who do not?
Easy living makes for weak living?
Does this explain a lot about the weakness of comfortable christianity?
