"The world is ripening for its destruction. God can bear with sinners but a little longer. They must drink the dregs of the cup of His wrath unmixed with mercy. Those who will be heirs of God, and joint heirs with Christ to the immortal inheritance, will be peculiar. Yes, so peculiar that God places a mark upon them as His, wholly His. Think ye that God will receive, honor, and acknowledge a people so mixed up with the world that they differ from them only in name? Read again Titus 2:13-15 . It is soon to be known who is on the Lord's side, who will not be ashamed of Jesus. Those who have not moral courage to conscientiously take their position in the face of unbelievers, leave the fashions of the world, and imitate the self-denying life of Christ, are ashamed of Him, and do not love His example. 1T 287.1"
"Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ; Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works. These things speak, and exhort, and rebuke with all authority. Let no man despise thee."
Ellen White directly references Titus 2:13-15 in this passage.
"valued His service, and the freedom He had so miraculously given them, more highly than the indulgences they enjoyed in Egypt while in servitude to a tyrannical, idolatrous people. 1T 287.2"
"And I am come down to deliver them out of the hand of the Egyptians, and to bring them up out of that land unto a good land and a large, unto a land flowing with milk and honey; unto the place of the Canaanites, and the Hittites, and the Amorites, and the Perizzites, and the Hivites, and the Jebusites."
Both passages discuss God delivering the Israelites from Egypt. While Exodus 3:8 focuses on the destination, the underlying theme of deliverance is shared.
"I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage."
The EGW passage refers to the Exodus and the Israelites' freedom from Egypt. The verse is the first of the Ten Commandments, reminding the Israelites of God's deliverance. While not a direct quote, the EGW passage echoes the theme of liberation from bondage.
