Genesis 4:9 And the Lord said unto Cain, 10 The voice of thy brother's blood crieth unto me from the ground. 11 And now art thou cursed from the earth, 12 When thou tillest the ground, it shall not henceforth yield unto thee her strength.
[Patriarchs & Prophets pp 90] In the days of Noah a double curse was resting upon the earth in consequence of Adam's transgression and of the murder committed by Cain. Yet this had not greatly changed the face of nature. There were evident tokens of decay, but the earth was still rich and beautiful in the gifts of God's providence. The hills were crowned with majestic trees supporting the fruit-laden branches of the vine. The vast, garden-like plains were clothed with verdure, and sweet with the fragrance of a thousand flowers. The fruits of the earth were in great variety, and almost without limit.
The trees far surpassed in size, beauty, and perfect proportion any now to be found; their wood was of fine grain and hard substance, closely resembling stone, and hardly less enduring. Gold, silver, and precious stones existed in abundance. The human race yet retained much of its early vigor. But a few generations had passed since Adam had access to the tree which was to prolong life; and man's existence was still measured by centuries.
Had that long-lived people, with their rare powers to plan and execute, devoted themselves to the service of God, they would have made their Creator's name a praise in the earth, and would have answered the purpose for which He gave them life. But they failed to do this. There were many giants, men of great stature and strength, renowned for wisdom, skillful in devising the most cunning and wonderful works; but their guilt in giving loose rein to iniquity was in proportion to their skill and mental ability.
Genesis 6:4 There were giants in the earth in those days; and also after that, when the sons of God came in unto the daughters of men, and they bare children to them, the same became mighty men which were of old, men of renown.
May God add His blessing to the study of His word. “Good night” and God bless!
