"acquainted with God, who made all the beautiful things which attract and delight them. She can lead their minds up to their Creator and awaken in their young hearts a love for their heavenly Father, who has manifested so great love for them. Parents can associate God with all His created works. The only schoolroom for children from eight to ten years of age should be in the open air amid the opening flowers and nature's beautiful scenery. And their only textbook should be the treasures of nature. These lessons, imprinted upon the minds of young children amid the pleasant, attractive scenes of nature, will not be soon forgotten. 3T 137.2"
"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 emphasize the importance of observing God's creation to understand His attributes and character. EGW expands on this by suggesting nature as a schoolroom, directly aligning with the principle in Romans 1:20.
