When God created man, He planned that the man will live for a very long time. The Bible we are told mentioned two lifespans for man:
120 years as a limit set by God in Genesis 6:3, and 70-80 years as a common lifespan in Psalm 90:10.
Genesis 6:3 states thus, My Spirit shall not strive with man forever, for he is indeed flesh yet his days shall be one hundred and twenty years.
However, again in Psalm 90:10, the Bible says that, The days of our life are seventy years, stating that by reason of strength , man could go up to eighty years.
Whether 70 or 80, Gods grace is definitely on one humble and simple man, a man who has touched and still touching lives. He was celebrated last week for crossing both limits stated in Psalms 90:10.
