The opinion is held by many that God placed a separating wall between the Hebrews and the outside world; that His care and love, withdrawn to a great extent from the rest of mankind, were centered upon Israel. But God did not design that His people should build up a wall of partition between themselves and their fellow men. The heart of Infinite Love was reaching out toward all the inhabitants of the earth. Though they had rejected Him, He was constantly seeking to reveal Himself to them and make them partakers of His love and grace. His blessing was granted to the chosen people, that they might bless others. (PP 368.1) MC VC

God called Abraham, and prospered and honored him; and the patriarch’s fidelity was a light to the people in all the countries of his sojourn. Abraham did not shut himself away from the people around him. He maintained friendly relations with the kings of the surrounding nations, by some of whom he was treated with great respect; and his integrity and unselfishness, his valor and benevolence, were representing the character of God. In Mesopotamia, in Canaan, in Egypt, and even to the inhabitants of Sodom, the God of heaven was revealed through His representative. (PP 368.2) MC VC

So to the people of Egypt and of all the nations connected with that powerful kingdom, God manifested Himself through Joseph. Why did the Lord choose to exalt Joseph so highly among the Egyptians? He might have provided some other way for the accomplishment of His purposes toward the children of Jacob; but He desired to make Joseph a light, and He placed him in the palace of the king, that the heavenly illumination might extend far and near. By his wisdom and justice, by the purity and benevolence of his daily life, by his devotion to the interests of the people—and that people a nation of idolaters—Joseph was a representative of Christ. In their benefactor, to whom all Egypt turned with gratitude and praise, that heathen people were to behold the love of their Creator and Redeemer. So in Moses also God placed a light beside the throne of the earth’s greatest kingdom, that all who would, might learn of the true and living God. And all this light was given to the Egyptians before the hand of God was stretched out over them in judgments. (PP 368.3) MC VC
