Since mankind lost or neglected the truth about God's Sabbath, the Creator chose to reveal it again when He was in the process of making Israel into His Servant-Nation. God instructed them, in order that they could teach others: "Remember the Sabbath day to keep it holy. Six days you shall labor and do all your work, but the seventh day is the Sabbath of the LORD your God. In it you shall do no work.... For in six days the LORD made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the LORD blessed the Sabbath day and hallowed it" (Ex. 20:8-11).
Notice: God claims the Sabbath as His. He doesn't refer to it as the "Jewish Sabbath." Though it became known as that to distinguish it from the various pagan days of worship (Ga. 4:10). "The Lord's day" was meant for all mankind to enjoy and appreciate (Matt. 12:8; Isa. 56:6). And the early Church, composed of both Jews and Gentiles, did celebrate the proper Sabbath together for over THREE HUNDRED YEARS! That's longer than the U.S. has known independence.
When God restored the Sabbath to Israel, it was the same seventh day Sabbath instituted at Creation. It wasn't changed to a different day. And its purpose remained the same: to reveal the CREATOR and commemorate His majestic works of art.
Jesus honored His Father by keeping God's commandments. The fourth commandment is to remember the Sabbath day. Christ didn't forget the importance of attending Sabbath services (Luke 4:16) - NEVER ON A SUNDAY- and the apostle Paul encourages us to avoid the habit of skipping Church services (Heb. 10:25). After all, it is a commanded assembly (Lev. 23:3) that offers us a chance to better understand the Scriptures (Acts 19:8). Why miss out?
As well as reminding us of God's awesome ability, the Sabbath is a memorial of Israel's deliverance from Egypt (Deut. 5:15). It also foreshadows our future redemption from European tyranny and portrays our ongoing deliverance from sin (Isa. 14:3; Ga. 5:1). The plagues God sent against Egypt identified Him as the Creator God: the One who could control the forces of nature and intervene in the affairs of nations. When God pours out the seven last plagues on Europe's Babylonish system, bringing it to its knees, it'll reveal Him alone as the Most High God and Holy Father (Dan. 2:44; Rev. 14:7).
This Sabbath question is destined to become a bloody issue again (Rev. 13:17; 14:13). But for those who really want to know the truth, God's entrusted the Jews to keep the knowledge of the true Sabbath day (Rom. 9:4). And the Jews don't worship on Sunday! They follow the biblical practice of celebrating the Sabbath: from Friday sunset to Saturday sunset. God even pronounces a blessing on everyone who's properly keeping the Sabbath just before Christ's return, despite political pressure to do otherwise (Isa. 56:1-2).
Why not take time out to get to know God? Although He enjoys our contact daily, God's set aside every seventh day as a special opportunity to learn more about Him and life. Don't settle for counterfeits or attempt to adopt days copied from others (Deut. 12:30).
God's reserved the Sabbath day for His People. It was a regular part of Jesus' life and the early Church's custom. In fact, all the righteous priests and prophets, patriarchs and kings, throughout biblical history, have kept God's holy Sabbath. Why not follow their example? Don't forget!
