For if Joshua had given them rest, God would not have spoken later about another day. Therefore, a Sabbath rest remains for God’s people. 10 For the person who has entered His rest has rested from his own works, just as God did from His. Let us then make every effort to enter that rest, so that no one will fall into the same pattern of disobedience. Hebrews 4:8-11
From the beginning, God created man to have a relationship with Him. The Sabbath was that weekly opportunity to commune with God, that God established at the foundation of the world and preserved through the millennia. It looks back to creation and deliverance from Egypt, and it looks forward to the ultimate rest of God and His people in the New Heavens and New Earth. It is a weekly reminder to all who worship the Creator of His majesty, loyalty, loving kindness, and life-giving power. We can find rest and peace in God, on God’s Sabbath day.
