"For as I passed by, and beheld your devotions, I found an altar with this inscription, TO THE UNKNOWN GOD. Whom therefore ye ignorantly worship, him declare I unto you."
EGW directly quotes and elaborates on the concept of the 'unknown God' mentioned in Acts 17:23. This is a clear and explicit allusion.
"Today the truths of Scripture are to be brought before the great men of the world in order that they may choose between obedience to God's law and allegiance to the prince of evil. God sets everlasting truth before them—truth that will make them wise unto salvation, but He does not force them to accept it. If they turn from it, He leaves them to themselves, to be filled with the fruit of their own doings. AA 241.2"
"I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live:"
Both passages highlight the principle of God setting choices before people (obedience/disobedience, life/death) and allowing them to choose. EGW applies this principle to the context of accepting or rejecting the truths of Scripture, echoing the sentiment in Deuteronomy.
"And ye shall know the truth, and the truth shall make you free."
Both passages connect truth with freedom/salvation and the consequences of rejecting it. EGW amplifies the idea that truth leads to salvation and the choice people have.
"“The preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God. For it is written, I will destroy the wisdom of the wise, and will bring to nothing the understanding of the prudent.” “God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty; and base things of the world, and things which are despised, hath God chosen, yea, and things which are not, to bring to nought things that are.” 1 Corinthians 1:18, 19, 27, 28 . Many of the greatest scholars and statesmen, the world's most eminent men, will in these last days turn from the light because the world by wisdom knows not God. Yet God's servants are to improve every opportunity to communicate the truth to these men. Some will acknowledge their ignorance of the things of God and will take their place as humble learners at the feet of Jesus, the Master Teacher. AA 241.3"
