What does the Bible say about Sabbath keeping?

Sabbath keeping is emphasized distinctly in scripture as a means of acknowledging God's sanctifying grace. In Exodus 31:13, God commands His people to keep the Sabbath as a sign between Him and them, signifying that He is the one who sanctifies them. This practice is not a matter of indifference or personal preference; rather, it presents a direct connection to God’s promise of salvation. As a ceremonial sign, the Old Testament Sabbath pointed towards the ultimate rest found in Jesus Christ, who fulfills this need for rest through His completed work on the cross. Thus, understanding the significance of the Sabbath is crucial for grasping the entire redemptive story found in the Scriptures.
