Thanks, Br. Richard for posting this info. Here are excerpts from Testimonies for the Church, Vol. 6, pp. 349-368, The Observance of the Sabbath, that should be of interest to all.
"... 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 Sabath 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.
"...The Sabbath is a golden clasp that unites God and His people. But the Sabbath command has been broken. God's holy day has been desecrated. The Sabbath has been torn from its place by the man of sin, and a common working day has been exalted in its stead. A breach has been made in the law, and this breach is to be repaired. The true Sabbath is to exalted to its rightful position as God's rest day....
"...The Sabbath question is to be the issue in the great final conflict in which all the world will act a part. Men have honored Satan's principles above the principles that rule in the heavens. They have accepted the spurious sabbath, which Satan has exalted as the sign of his authority. But God has set His seal upon His royal requirement....God has called us to uplift the standard of His downtrodden Sabbath.
"...All through the week we are to have the Sabbath in mind and be making preparation to keep it according to the commandment. We are not merely to observe the Sabbath as a legal matter. We are to understand its spiritual bearing upon all the transactions of life. All who regard the Sabbath as a sign between them and God, showing that He is the God who sanctifies them, will represent the principles of His government. They will bring into daily practice the laws of His Kingdom. Daily it will be their prayer that the sanctification of the Sabbath may rest upon them. Every day they will have the companionship of Christ and will exemplify the perfection of His character. Every day their light will shine forth to others in good works." --Ellen White.
God's Law Immutable, pp. 433-450 in The Great Controversy, by the same author should be read, as it contains a wealth of information on the subject....
"Remember the Sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work: But the seventh day is the Sabbath of the Lord thy God: in it thou shalt not do any work, thou, nor thy son, nor thy daughter, thy manservant, nor thy maidservant, nor thy cattle, nor thy stranger that is withink thy gates: For in six days the Lord made heaven and earth, the sea, and all that in them is, and rested the seventh day: wherefore the Lord blessed the Sabbath day, and hallowed it." Exodus 20 8-11.
