Nature was their lessonbook. In the Garden of Eden the existence of God was demonstrated, His attributes were revealed, in the objects of nature that surrounded them. Everything upon which their eyes rested spoke to them. The invisible things of God, “even His everlasting power and divinity,” were clearly seen, being understood by the things that were made. {8T 255.2}

Naturen var deres lektiebog. I edens have blev Guds eksistens vist, hans egenskaber åbenbaret i naturen, som omgav dem. Alt hvad deres øjne hvilede på talte til dem. Guds usynlige ting "endog hans evige kraft og guddommelighed," blev set klart og blev forstået ved de ting som var frembragt.
