"Love, the basis of creation and of redemption, is the basis of true education. This is made plain in the law that God has given as the guide of life. The first and great commandment is, “Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind.” Luke 10:27 . To love Him, the infinite, the omniscient One, with the whole strength, and mind, and heart, means the highest development of every power. It means that in the whole being—the body, the mind, as well as the soul—the image of God is to be restored. Ed 16.1"
"And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself."
Ellen White directly references Luke 10:27 in this passage.
"Like the first is the second commandment—“Thou shalt love thy neighbor as thyself.” Matthew 22:39 . The law of love calls for the devotion of body, mind, and soul to the service of God and our fellow men. And this service, while making us a blessing to others, brings the greatest blessing to ourselves. Unselfishness underlies all true development. Through unselfish service we receive the highest culture of every faculty. More and more fully do we become partakers of the divine nature. We are fitted for heaven, for we receive heaven into our hearts. Ed 16.2"
"And the second is like unto it, Thou shalt love thy neighbour as thyself."
Ellen White directly references Matthew 22:39 in this passage.
Since God is the source of all true knowledge, it is, as we have seen, the first object of education to direct our minds to His own revelation of Himself. Adam and Eve received knowledge through direct communion with God; and they learned of Him through His works. All created things, in their original perfection, were an expression of the thought of God. To Adam and Eve nature was teeming with divine wisdom. But by transgression man was cut off from learning of God through direct communion and, to a great degree, through His works. The earth, marred and defiled by sin, reflects but dimly the Creator's glory. It is true that His object lessons are not obliterated. Upon every page of the great volume of His created works may still be traced His handwriting. Nature still speaks of her Creator. Yet these revelations are partial and imperfect. And in our fallen state, with weakened powers and restricted vision, we are incapable of interpreting aright. We need the fuller revelation of Himsel…
"For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:"
Both passages discuss how creation reveals God's nature, but that sin has marred our ability to fully understand it. EGW expands on the idea that we need a 'fuller revelation' because of our fallen state, which directly echoes the need for Christ as a redeemer.
"And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;"
EGW's statement about the earth being 'marred and defiled by sin' and reflecting 'but dimly the Creator's glory' directly relates to the curse on the ground in Genesis 3:17. Both passages connect sin with a degradation of the natural world and a loss of ease in obtaining knowledge or sustenance from it.
