“Surely My Sabbaths you shall keep, for it is a sign between Me and you throughout your generations, that you may know that I am the LORD who sanctifies you.”—Exodus 31:13 JNN 193.1
As the Sabbath was the sign that distinguished Israel when they came out of Egypt to enter the earthly Canaan, so it is the sign that now distinguishes God’s people as they come out from the world to enter the heavenly rest. The Sabbath is a sign of the relationship existing between God and His people, a sign that they honor His law. It distinguishes between His loyal subjects and transgressors. JNN 193.2
From the pillar of cloud Christ declared concerning 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” (Exodus 31:13). The Sabbath given to the world as the sign of God as the Creator is also the sign of Him as the Sanctifier. The power that created all things is the power that re-creates the soul in His own likeness. To those who keep holy the Sabbath day it is the sign of sanctification. True sanctification is harmony with God, oneness with Him in character. It is received through obedience to those principles that are the transcript of His character. And the Sabbath is the sign of obedience. He who from the heart obeys the fourth commandment will obey the whole law. He is sanctified through obedience. JNN 193.3
To us as to Israel the Sabbath is given “for a perpetual covenant.” To those who reverence His holy day the Sabbath is a sign that God recognizes them as His chosen people. It is a pledge that He will fulfill to them His covenant. Every soul who accepts the sign of God’s government places himself under the divine, everlasting covenant. He fastens himself to the golden chain of obedience, every link of which is a promise. JNN 193.4
The fourth commandment alone of all the ten contains the seal of the great Lawgiver, the Creator of the heavens and the earth. Those who obey this commandment take upon themselves His name, and all the blessings it involves are theirs.—Testimonies for the Church 6:349, 350. JNN 193.5
Further Reflection: If sanctification is the process of being made holy, how does Jesus use the Sabbath to sanctify me? Is my Sabbath observance making me more holy? JNN 193.6
