Genesis 1:31] And God saw everything that he had made, and behold, it was very good. And there was evening and there was morning, the sixth day.
[2:1] Thus the heavens and the earth were finished, and all the host of them.  And on the seventh day God finished his work that he had done, and he rested on the seventh day from all his work that he had done.  So God blessed the seventh day and made it holy, because on it God rested from all his work that he had done in creation.
Why did God “rest”? His rest was not a rest of exhaustion. Rather God stopped working on creation because his work was “finished” and it “was very good.” His action of stopping confirmed what he said earlier – it was very good. The world was perfectly suited for mankind and perfectly displayed the glories of its Creator. His rest was his stamp of approval. It was good news that his provision was perfect. By keeping the Sabbath, God’s people were proclaiming that His provision is all they need in their lives.
In the New Testament, Christians, the spiritual Israelites, start the week with the Lord’s Day. Sunday is the first day of the week, not the last. We don’t drudge through the week hoping for a good weekend. Rather, we start with the resurrection power of Sunday and its energy spills over into the rest of the week.
In other words, Sundays are of mega-importance because the way we worship on Sunday effects the way we work on Monday. Another way to say it is that our GRACE ETHIC drives our WORK ETHIC. Grace first. Gospel first. The gospel is the soil out of which our work blossoms. We work out of our forgiven-ness, not as a path to it. Get drenched with the Gospel this Sunday and start your week right.
Prayer: Lord, we see how important Lord’s Day services are. Be with the church of Jesus Christ as we gather tomorrow in different local congregations. May Jesus be lifted up high; may the people of God be fed by your Word and inundated with your Spirit; and may the world be reached in our generation.
