The psalmist said that our days on earth “are seventy years; and if by reason of strength they are eighty years, yet their boast is only labor and sorrow” (Psalm 90:10). So man, according to the Psalms, has seventy years, and sometimes by reason of strength, eighty years or more. Now that is the average for modern man.
…But if you go back to the days of the patriarchs in Israel, one hundred thirty, one hundred forty or one hundred fifty years was not uncommon. If you go all the way back to the days just following creation, men lived nine hundred years or more. I wonder if, when the Millennium comes and there is no more sin on earth, people will once again live two hundred or three hundred years, or even longer.
