"Many illustrations from nature are used by the Bible writers, and as we observe the things of the natural world, we shall be enabled, under the guiding of the Holy Spirit, more fully to understand the lessons of God's word. It is thus that nature becomes a key to the treasure house of the word. Ed 120.1"
"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 connect understanding the natural world with understanding spiritual truths. Romans 1:20 states that God's invisible qualities are understood through creation, and the EGW passage suggests that nature can help us understand the lessons of God's word. The EGW passage builds upon the idea presented in Romans 1:20.
