For most of my life, as a kid and later as an adult, Sundays were busy. We got up, put on our "Sunday best," and "went to church." This included both Sunday School and Worship Service. Then we would usually do the same thing again at night, except this time we didn't have to dress up (not sure why). We were busy for God - or so we thought - on what we considered to be the Sabbath. On what we believed was God's ordained day of rest for us we kept busy all day.
I now realize that Jesus Christ is our Sabbath rest. How freeing this is! We are no longer under Old Covenant regulations and practices. Jesus fulfilled the law so we don't have to. He has also freed us from sin to live restfully in his great grace. Christ is our 24/7 Sabbath rest.
Now Sundays are actually restful. Sometimes we get together with friends, but sometimes we don't. We relax a lot. We don't dress up. We read. We take naps. We watch movies. We play games. Sometimes we stroll around Savannah's historic district or go to the beach. We don't worry about being busy for God. Because of this, we actually rest.
I thank the Lord that his rest is not limited to one day per week. Since the Sabbath never ends, we can truly rest in Christ at all times - even on Sundays.
