Kristine, that is a good point. My husband was recently out of work for almost three months, and we found out it's not so easy to just get a job at McDonalds (or any other restaurant) like everybody says. This is because we refused to work on Sunday: in the city where we lived, there was a church about every three blocks, and Sunday was the biggest day for restaurants with the "after church" crowd. We had quite a few people tell us that our lack of Sunday availability was killing our chances of being hired in the food industry-- how ironic that Christians who would not themselves work on Sunday, but would go out to eat, were the primary cause of a situation where other Christians could not get jobs to provide food for their families.
I am not sure where to draw the line with this: I have felt guilty about even making the bed on Sunday (after all, is that really a work of mercy?), until I read the account in John where Christ healed the lame man on the Sabbath, and then commanded him to "take up his bed...". He was not to just leave it there in a pile, but to "straighten up" after himself.
'I cannot live like Jesus, example though he be
For he was strong and selfless, and I am tied to me.
But I have asked my Jesus to live his life in me . . .
Behold his warm, his tangible, his dear humanity.' -Betty Stam
