In Education:
Although the earth was blighted with the curse, nature was still to be man's lesson book. It could not now represent goodness only; for evil was everywhere present, marring earth and sea and air with its defiling touch. Where once was written only the character of God, the knowledge of good, was now written also the character of Satan, the knowledge of evil. From nature, which now revealed the knowledge of good and evil, man was continually to receive warning as to the results of sin. {26.2}
In drooping flower and falling leaf Adam and his companion witnessed the first signs of decay. Vividly was brought to their minds the stern fact that every living thing must die. Even the air, upon which their life depended, bore the seeds of death. {26.3}
Continually they were reminded also of their lost dominion. Among the lower creatures Adam had stood as king, and so long as he remained loyal to God, all nature acknowledged his rule; but when he transgressed, this dominion was forfeited. The spirit of rebellion, to which he himself had given entrance, extended throughout the animal creation. Thus not only the life of man,
but the nature of the beasts, the trees of the forest, the grass of the field, the very air he breathed, all told the sad lesson of the knowledge of evil. {26.4}
But man was not abandoned to the results of the evil he had chosen. In the sentence pronounced upon Satan was given an intimation of redemption. "I will put enmity between thee and the woman," God said, "and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel." Genesis 3:15. This sentence, spoken in the hearing of our first parents, was to them a promise. Before they heard of the thorn and the thistle, of the toil and sorrow that must be their portion, or of the dust to which they must return, they listened to words that could not fail of giving them hope. All that had been lost by yielding to Satan could be regained through Christ. {27.1}
This intimation also nature repeats to us. Though marred by sin, it speaks not only of creation but of redemption. Though the earth bears testimony to the curse in the evident signs of decay, it is still rich and beautiful in the tokens of life-giving power. The trees cast off their leaves, only to be robed with fresher verdure; the flowers die, to spring forth in new beauty; and in every manifestation of creative power is held out the assurance that we may be created anew in "righteousness and holiness of truth." Ephesians 4:24, margin. Thus the very objects and operations of nature that bring so vividly to mind our great loss become to us the messengers of hope. {27.2}
I thought I'd read that Adam & Eve cried when the first leaf fell, or the first flower died. I can't remember exactly how the quote goes. It is a pity we are so used to seeing death. Many have become calloused except by the most horrific crimes. It will be a wonder to see all life made new, no death. Imagine picking a flower and it will never die - incredible.
