"Chapter 19—Worldliness in the Church It is recorded of the holy men of old that God was not ashamed to be called their God. The reason assigned is that instead of coveting earthly possessions or seeking happiness in worldly plans or aspirations they placed their all upon the altar of God and made disposition of it to build up His kingdom. They lived only for God's glory and declared plainly that they were strangers and pilgrims on earth, seeking a better country, that is, an heavenly. Their conduct proclaimed their faith. God could entrust to them His truth and could leave the world to receive from them a knowledge of His will. 5T 188"
"But now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city."
EGW directly references and expands upon Hebrews 11:16, including the phrase 'God is not ashamed to be called their God' and the concept of seeking a 'better country, that is, an heavenly.' This is a clear and intentional allusion.
