Here are the quotes on the picture, followed by their context (all-caps added for emphasis):
“THE INSTRUCTIONS GIVEN TO MOSES WERE RECORDED FOR THE BENEFIT OF ALL WHO SHOULD LIVE UPON THE EARTH TO THE CLOSE OF TIME. GOD has spoken; let us listen to His words and obey them.” (Christ Triumphant, p. 109, by Ellen G. White)
“We are to listen to the voice of CHRIST speaking in the creation of the world and from the pillar of cloud, for our eternal welfare depends upon our obedience to the voice of GOD. Let all move guardedly. LET US NOT PASS BY ANYTHING THAT CHRIST HAS GIVEN THROUGH THE HOLY PEOPLE OF OLD FOR THE BENEFIT OF EVERY GENERATION.” (Ibid, p. 188)
“IF YE LOVE ME, KEEP MY COMMANDMENTS.” (John 14:15 KJV)
“The Lord suffered His people Israel to go into bondage in Egypt because they did not walk in His ways but dishonored Him by their continual transgressions. Here, subjected to oppression and hard servitude, they could not keep God’s Sabbath, and by their long mingling with a nation of idolaters their faith became confused and corrupted. Association with the ungodly and unbelieving will have the same influence upon those who believe the present truth unless they keep the Lord ever before them so that His Spirit shall be their shield. . . .
“Pharaoh saw the mighty working of the Spirit of God; he saw the miracles the Lord performed by His servant; but he refused obedience to God’s command. The rebellious king had proudly inquired, “Who is the Lord, that I should obey his voice to let Israel go? I know not the Lord, neither will I let Israel go.” And as the judgments of God fell more and more heavily upon him, he persisted in stubborn resistance. By rejecting light from heaven, he became hard and unimpressible. . . . Those who exalt their own ideas above the plainly specified will of God are saying, as did Pharaoh, “Who is the Lord, that I should obey his voice?” Every rejection of light hardens the heart and darkens the understanding; and thus people find it more and more difficult to distinguish between right and wrong, and they become bolder in resisting the will of God.
“The Lord brought Israel from Egypt, that they might keep His Sabbath, and He gave them special directions how to keep it. THE INSTRUCTIONS GIVEN TO MOSES WERE RECORDED FOR THE BENEFIT OF ALL WHO SHOULD LIVE UPON THE EARTH TO THE CLOSE OF TIME. GOD HAS SPOKEN; LET US LISTEN TO HIS WORDS AND OBEY THEM.
“When the manna was given, the people were tested upon God’s law. Then said the Lord to the children of Israel through Moses, “I will rain bread from heaven for you; and the people shall go out and gather a certain rate every day, that I may prove them, whether they will walk in my law, or no.”. . .
“Notwithstanding this special direction of God, some did go out to gather manna on the seventh day, but they found none; and the Lord said unto Moses, “How long refuse ye to keep my commandments and my laws?” That there might be no mistake in the matter, the Father and the Son descended upon Mount Sinai, and there the precepts of His law were spoken in awful grandeur in the hearing of all Israel.” (Christ Triumphant, p. 109, by Ellen G. White)
“The instruction given in the Old Testament Scriptures is as verily the word of Christ as the instruction in the New Testament. Christ was as verily humanity’s Redeemer in the days when the Old Testament was written as He was when He appeared in the form of a man. He gave those of ancient Israel just as favorable an opportunity of working out their own salvation as He did those who listened to His words.
“A character formed after the divine likeness is the only treasure that people can take from this world to the next. The character as formed in this world determines one’s destiny for eternity. The element of value in one’s life in this world will be of value in the world to come. A person’s future is determined by the way one allows himself or herself to be influenced. If one cherishes and cultivates hereditary tendencies for wrong, indulging fleshly inclinations, appetites, and passions, that individual can never enter the kingdom of God. But the person who strives to repress evil inclinations, who is willing to be governed by the Spirit of Jesus Christ, is transformed. . . .
“Christ’s character was exemplified in Abel, Noah, Seth, Enoch, Abraham, Joseph, Moses, Joshua, Samuel, David, and all the host of those recorded as having characters that God could approve. [As examples], we are also given Cain and all who form characters opposite to truth, fidelity, obedience, and righteousness. All had an opportunity to show themselves members of the Cain family, or as members of the royal family. . . . Purity and holiness come only through Christ. . . .
“WE ARE TO LISTEN TO THE VOICE OF CHRIST SPEAKING IN THE CREATION OF THE WORLD AND FROM THE PILLAR OF CLOUD, FOR OUR ETERNAL WELFARE DEPENDS UPON OUR OBEDIENCE TO THE VOICE OF GOD. LET ALL MOVE GUARDEDLY. LET US NOT PASS BY ANYTHING THAT CHRIST HAS GIVEN THROUGH THE HOLY PEOPLE OF OLD FOR THE BENEFIT OF EVERY GENERATION.
“All that God’s mind has planned, that His hand has touched, are lessons written for our admonition upon whom the ends of the world are come. Those things that have been will be. Christ’s words of approval or disapproval come sounding down along the line of our time. Our spiritual and eternal interests are involved in the facts stated. The Lord means what He says, and says what He means.” (Christ Triumphant, p. 188, by Ellen G. White)
