How do we know the Sabbath is important for Christians?

The Sabbath serves as a vital rhythm of rest and worship for Christians, reflecting God's original design. It is not merely a legalistic requirement but a gracious provision for our well-being. After Christ's resurrection, Christians observe the first day of the week—often referred to as the Lord's Day—to commemorate His victory over sin and death. This change from the seventh to the first day symbolizes the new creation and the fulfillment of the Sabbath's purpose in Christ, who invites believers to find their rest in Him. As such, the Sabbath embodies both physical rest and spiritual refreshment, pointing towards eternal rest in Him.
