Moses, the man of God approached Him in an attitude of humility and praise. He recognized and confessed the greatness of God and the weakness of man—that God had an existence from “everlasting to everlasting” before the ancient mountains and the earth were formed.
Time is meaningless to God, but to man, seventy or eighty years is a lifetime. Even a thousand years to God are like a brief period of a guard watch in the night or a flash flood. Moses prayed that we might have the wisdom to use our time for God.
Man must realize his frailty, but also his strengths. His existence is for the purpose of serving God and leaving a legacy of faith for future generations. At the end of his life, Moses could look back at a life of faithful service to God and to his fellow man. He had his shortcomings as does all mankind. His prayer contained a plea for God to extend His mercy to all.
