When I was called for jury duty and during voir dire, one attorney as me if civil disobedience was ever permissible. I don’t remember exactly what I said (over three decades ago) – it might not have been “absolutely”, but it was firm enough to indicate that I would not be easily dissuaded. Whereupon I was excused. 
I was actually a little disappointed, because it would have been interesting.
Agreed. He was Lord of the Sabbath in the OT as well, however, and never disobeyed it in the New. He was, however, justifiably distressed with the Pharisees when they interpreted picking grain for a
snack as labor (“harvesting”), and that healing was too, neglecting mercy. “Mercy trumps law” as it did in the Old Testament, as well. (Interestingly, the OT was more liberal than many in our culture when it comes to eating an apple for a snack from a neighbor’s tree. Just don’t bring a bushel basket.)
When working with or for a neighbor demonstrates mercy (which would include pointing them to the Lord), no problem. Routine causal commerce – including eating out or ordering in – is another discussion. I did buy ice for a church dinner, though (gasp ), when someone else had forgotten, and have more than once bought gas for extended drives that had come up unexpectedly. And when traveling with or meeting others (not necessarily Christians) and eating out, legalistic protestations are not appropriate (and never are). Routine blatant and wanton disobedience might call for some discipline, though, as it would for any other of the ‘Big Ten’?
