"In this age, life has become artificial, and men have degenerated. While we may not return fully to the simple habits of those early times, we may learn from them lessons that will make our seasons of recreation what the name implies—seasons of true upbuilding for body and mind and soul. Ed 211.3"
"And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God."
Both passages encourage not conforming to the world. Romans 12:2 is a direct call to transformation and non-conformity, while EGW applies this principle to lifestyle choices and recreation.
"Thus saith the Lord, Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest for your souls. But they said, We will not walk therein."
Both passages encourage a return to older, simpler ways. Jeremiah speaks of finding the 'good way' in the 'old paths,' while EGW suggests learning from the 'simple habits of those early times.'
"the benefit of nature's teaching, and recreation amidst her surroundings. It would be a great aid in educational work could every school be so situated as to afford the pupils land for cultivation, and access to the fields and woods. Ed 211.4"
"And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth."
The EGW quote echoes the Genesis verse's call to cultivate and have dominion over the earth, applying it to the context of education and the benefits of interacting with nature. However, the connection is somewhat broad and thematic, hence the slightly reduced confidence.
