What does the Bible say about keeping the Sabbath?

The Bible outlines the necessity of keeping the Sabbath through both the Old and New Testaments. In Exodus 20:8-11, we see God's command to remember the Sabbath day and keep it holy, highlighting its origin in the creation account where God rested on the seventh day. This day is not merely for physical rest but also serves as a sign of God’s deliverance, as seen in Deuteronomy 5:12-15, where the Israelites are reminded of their past slavery in Egypt and the Lord's mighty hand that freed them. Today, Christians observe the Lord's Day as a parallel to the Sabbath, considering it a day for worship and communion with God, reflecting our spiritual rest in Jesus Christ.
