Inspired by this question: What qualifies as work on Sunday?
I know some churches are very specific that we should commit one weekday to the Lord (Saturday or Sunday). Much like Jews celebrate the Sabbath.
The need to rest one day a week is very real for me. I really find it necessary to take one day off work, studies and all that. I usually do this on Sunday, as it's usually practical. However, if I need to do something on Sunday, I have no problem with instead taking the following Tuesday off, resting, reading and praying. This seems to work well for me.
I've never found a reason to specify the weekday I should spend like Lord's day. Are there any?
