When we remember that two thirds of the world’s inhabitants today are idolaters, and that since the fall, idolatry, with its train of associated and resultant evils, has ever been a prevailing sin, and then think that the observance of the Sabbath, as God ordained it, would have prevented all this, we can better appreciate the value of the Sabbath institution, and the importance of Sabbath-keeping. 5. What does God say the Sabbath will be to those who hallow it, or keep it holy? “And hallow My Sabbaths; and _they shall be a sign between Me and you, that ye may know that I am the Lord your God_.” Eze. 20:20. 6. How important is it that we know God? “And _this is life eternal_, that they might know Thee the only true God, and Jesus Christ, whom Thou hast sent.” John 17:3. 7. Is there any danger of God’s chosen people forgetting Him? “_Beware that thou forget not the Lord thy God_, in not keeping His commandments, and His judgments, and His statutes.” Deut. 8:11. 8. What other reason is given for keeping the Sabbath? “Verily My Sabbaths ye shall keep: _for it is a sign between Me and you_ throughout your generations; _that ye may know that I am the Lord that doth __SANCTIFY__ you_.” Ex. 31:13. NOTE.—To sanctify is to make holy, or to set apart for a holy use. The sanctification, or making holy, of sinful beings can be wrought only by the creative power of God through Christ by the Holy Spirit. In 1 Cor. 1:30 we are told that Christ is made unto us “sanctification;” and in Eph. 2:10 it is said that “we are His workmanship, _created_ in Christ Jesus unto good works.” The Sabbath, therefore, is a sign of sanctification, and thus of what Christ is to the believer, because it is a reminder of the creative power of God as manifested in the work of regeneration. It is the sign of the power of God, therefore, in both creation and redemption. To the believer, it is the evidence, or sign, that he knows the true God, who, through Christ, created all things, and who, through Christ, redeems the sinner and makes him whole. 9. What special reason did the Israelites have for keeping the Sabbath? “_And remember that thou wast a servant in the land of Egypt, and that the Lord thy God brought thee out thence through a mighty hand and by a stretched-out arm_: therefore the Lord thy God commanded thee to keep the Sabbath day.” Deut. 5:15.
