Sabbath rest

Speaking of naps - why did we ever give up that idea of Sabbath rest?
For the past year we've tried, with very modest success, to practice a modified version of Sabbath rest. After church is over, on an ordinary Sunday, we have a quiet lunch and a quiet afternoon reading, napping, visiting. Afternoon shades into evening, and we have a light dinner, maybe watch a bit of television, listen to music, or read again, then to bed.
Ordinary Sundays, though, are sometimes hard to come by.
Part of the problem is that Sunday can be a good visiting day, and we like to visit. Maybe someone comes for dinner after church - and we enjoy that. Or someone is celebrating a holiday, a family event, or just wants to get together - we enjoy that, too.
When it comes to Sabbath rest, we are usually our own worst enemies.
Without that quiet day, that slow start, we notice the rest of the week seems more tightly wound. Somehow it seems to go faster, feels more like a roller coaster.
What was God's intent when He mandated the Sabbath?
We tend to think of it as a restriction, when perhaps really it's a freedom.
Setting time aside one day out of seven for wonder, worship, rest - how can that be a bad thing?
Perhaps it is our own priorities that are out of whack. Perhaps by overscheduling ourselves, we wound our own selves.
Perhaps God asks us to rest on that one day because rest is exactly what we need most.
