Psalms 90:10 The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labor and sorrow; for it is soon cut off, and we fly away.
[Patriarchs & Prophets pp 83] As the years of man have decreased, and his physical strength has diminished, so his mental capacities have lessened. There are men who now apply themselves to study during a period of from twenty to fifty years, and the world is filled with admiration of their attainments. But how limited are these acquirements in comparison with those of men whose mental and physical powers were developing for centuries! It is true that the people of modern times have the benefit of the attainments of their predecessors.
The men of masterly minds, who planned and studied and wrote, have left their work for those who follow. But even in this respect, and so far as merely human knowledge is concerned, how much greater the advantages of the men of that olden time! They had among them for hundreds of years him who was formed in God's image, whom the Creator Himself pronounced “good”—the man whom God had instructed in all the wisdom pertaining to the material world. Adam had learned from the Creator the history of creation.
He himself witnessed the events of nine centuries; and he imparted his knowledge to his descendants. The antediluvians were without books, they had no written records; but with their great physical and mental vigor, they had strong memories, able to grasp and to retain that which was communicated to them, and in turn to transmit it unimpaired to their posterity. And for hundreds of years there were seven generations living upon the earth contemporaneously, having the opportunity of consulting together and profiting each by the knowledge and experience of all.
Romans 1:21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. 22 Professing themselves to be wise, they became fools.
May The Lord add His blessing to the study of His word. God bless!
