"The children of Israel were to occupy all the territory which God appointed them. Those nations that rejected the worship and service of the true God were to be dispossessed. But it was God's purpose that by the revelation of His character through Israel men should be drawn unto Him. To all the world the gospel invitation was to be given. Through the teaching of the sacrificial service Christ was to be uplifted before the nations, and all who would look unto Him should live. All who, like Rahab the Canaanite, and Ruth the Moabitess, turned from idolatry to the worship of the true God, were to unite themselves with His chosen people. As the numbers of Israel increased they were to enlarge their borders, until their kingdom should embrace the world. COL 290.1"
"And he said, It is a light thing that thou shouldest be my servant to raise up the tribes of Jacob, and to restore the preserved of Israel: I will also give thee for a light to the Gentiles, that thou mayest be my salvation unto the end of the earth."
Both passages discuss Israel's role as a light to the Gentiles and the expansion of God's kingdom to include all nations. The EGW passage elaborates on this theme by mentioning Rahab and Ruth as examples of those who joined God's people.
"God desired to bring all peoples under His merciful rule. He desired that the earth should be filled with joy and peace. He created man for happiness, and He longs to fill human hearts with the peace of heaven. He desires that the families below shall be a symbol of the great family above. COL 290.2"
"For thus saith the Lord that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the Lord; and there is none else."
Both passages emphasize God's desire for the earth to be inhabited and filled with joy and peace. Isaiah 45:18 speaks of God creating the earth to be inhabited, and the EGW passage expands on this by stating God created man for happiness and desires to fill human hearts with peace.
"of Judah, judge, I pray you, betwixt Me and My vineyard. What could have been done more to My vineyard, that I have not done in it? Wherefore when I looked that it should bring forth grapes, brought it forth wild grapes? And now go to; I will tell you what I will do to My vineyard: I will take away the hedge thereof, and it shall be eaten up; and break down the wall thereof, and it shall be trodden down: and I will lay it waste; it shall not be pruned nor digged; but there shall come up briers and thorns: I will also command the clouds that they rain no rain upon it. For ... He looked for judgment, but behold oppression; for righteousness, but behold a cry.” Isaiah 5:3-7 . COL 290.3"
"And now, O inhabitants of Jerusalem, and men of Judah, judge, I pray you, betwixt me and my vineyard. What could have been done more to my vineyard, that I have not done in it? wherefore, when I looked that it should bring forth grapes, brought it forth wild grapes? And now go to; I will tell you what I will do to my vineyard: I will take away the hedge thereof, and it shall be eaten up; and break down the wall thereof, and it shall be trodden down: And I will lay it waste: it shall not be pruned, nor digged; but there shall come up briers and thorns: I will also command the clouds that they rain no rain upon it."
EGW directly quotes Isaiah 5:3-7.
"And now, O inhabitants of Jerusalem, and men of Judah, judge, I pray you, betwixt me and my vineyard. What could have been done more to my vineyard, that I have not done in it? wherefore, when I looked that it should bring forth grapes, brought it forth wild grapes? And now go to; I will tell you what I will do to my vineyard: I will take away the hedge thereof, and it shall be eaten up; and break down the wall thereof, and it shall be trodden down: And I will lay it waste: it shall not be pruned, nor digged; but there shall come up briers and thorns: I will also command the clouds that they rain no rain upon it. For the vineyard of the Lord of hosts is the house of Israel, and the men of Judah his pleasant plant: and he looked for judgment, but behold oppression; for righteousness, but behold a cry."
Ellen White directly references Isaiah 5:3-7 in this passage.
