"The Sign of Our Relationship to God By the observance of the Sabbath the children of Israel were to be distinguished from all other nations. “Verily My Sabbaths ye shall keep,” Christ said, “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.” “It is a sign between Me and the children of Israel forever: for in six days the Lord made heaven and earth, and on the seventh day He rested, and was refreshed.” “Wherefore the children of Israel shall keep the Sabbath, to observe the Sabbath throughout their generations, for a perpetual covenant.” Exodus 31:13, 17, 16 . 8T 198"
"Speak thou also unto the children of Israel, saying, 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."
EGW directly quotes Exodus 31:13.
"It is a sign between me and the children of Israel for ever: for in six days the Lord made heaven and earth, and on the seventh day he rested, and was refreshed."
EGW directly quotes Exodus 31:17.
"By proclaiming the Ten Commandments to the children of Israel with His own voice, God demonstrated their importance. In awful grandeur He made known His majesty and authority as Ruler of the world. This He did to impress the people with the sacredness of His law and the importance of obeying it. The power and glory with which the law was given reveal its importance. It is the faith once delivered to the saints by Christ our Redeemer speaking from Sinai. 8T 198.1"
"And God spake all these words, saying,"
EGW directly references the event of God speaking the Ten Commandments and emphasizes its importance, which is the core event described in Exodus 20:1.
"Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints."
Both passages refer to 'the faith once delivered to the saints.' While EGW connects it to the giving of the law at Sinai, and Jude refers to the gospel, there's a thematic overlap in the idea of a foundational, divinely given faith.
"The Sabbath is a sign of the relationship existing between God and His people, a sign that they are His obedient subjects, that they keep holy His law. The observance of the Sabbath is the means ordained by God of preserving a knowledge of Himself and of distinguishing between His loyal subjects and the transgressors of His law. This is the faith once delivered to the saints, who stand in moral power before the world, firmly maintaining this faith. 8T 198.3"
"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."
Both passages highlight the Sabbath as a sign between God and His people. Ezekiel 20:20 explicitly states this, and EGW elaborates on the implications of this sign in terms of obedience and knowledge of God.
"Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints."
Both passages discuss the importance of maintaining and contending for a specific faith or belief system. EGW connects Sabbath observance to this faith, while Jude speaks of the faith delivered to the saints.
