Isaiah 56:2 Blessed is the man that doeth this, and the son of man that layeth hold on it; that keepeth the Sabbath from polluting it, and keepeth his hand from doing any evil.” 6 “The sons of the stranger, that join themselves to the Lord, to serve him, and to love the name of the Lord, to be his servants, every one that keepeth the Sabbath from polluting it, and taketh hold of my covenant; 7 even them will I bring to my holy mountain, and make them joyful in my house of prayer.
[The Great Controversy pp 451>452] These words apply in the Christian age, as is shown by the context: “The Lord God which gathereth the outcasts of Israel saith, Yet will I gather others to him, beside those that are gathered unto him.” [Isaiah 56:8.] Here is foreshadowed the gathering in of the Gentiles by the gospel. And upon those who then honor the Sabbath, a blessing is pronounced. Thus the obligation of the fourth commandment extends past the crucifixion, resurrection, and ascension of Christ, to the time when his servants should preach to all nations the message of glad tidings.
The Lord commands by the same prophet, “Bind up the testimony, seal the law among my disciples.” [Isaiah 8:16.] The seal of God's law is found in the fourth commandment. This only, of all ten, brings to view both the name and the title of the Lawgiver. It declares him to be the Creator of the heavens and the earth, and thus shows his claim to reverence and worship above all others. Aside from this precept, there is nothing in the decalogue to show by whose authority the law is given. When the Sabbath was changed by the papal power, the seal was taken from the law.
The disciples of Jesus are called upon to restore it, by exalting the Sabbath of the fourth commandment to its rightful position as the Creator's memorial and the sign of his authority. “To the law and to the testimony.” While conflicting doctrines and theories abound, the law of God is the one unerring rule by which all opinions, doctrines, and theories are to be tested. Says the prophet, “If they speak not according to this word, it is because there is no light in them.” Isaiah 8:20.
Matthew 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill. 18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
May God add His blessing to the study of His word. “Good night” and God bless!
