Sunday-Sabbath-Worship, & Rest?

Sunday is typically the Sabbath. I had to work today. Yesterday was my Sabbath. What does a day of rest and worship look like for a contemporary Christian? How do I/we rest AND worship? Does it mean we refrain from all activity? Alternatively, does it mean that we do activities that are worshipful and life giving to others and ourselves in service to God? Regardless of the day you call the Sabbath and not referencing biblical evidence, I think it is both. What do you think?
