“You make mankind return to the dust, and say, “Return, O people!” You are aware of our sins; you even know about our hidden sins. The days of our lives add up to seventy years, or eighty, if one is especially strong. But even one’s best years are marred by trouble and oppression. Yes, they pass quickly and we fly away. So teach us to consider our mortality, so that we might live wisely.” Psalms 90:3, 8, 10, 12 NET https://bible.com/bible/107/psa.90.3-12.NET

The Old Testament writers did not have the hope the New Testament writers enjoyed because of their live encounter with God in Jesus, Who fulfilled the Old Covenant and instituted the New Covenant by rising from the dead. This is the sure hope of the Christian that he will certainly die in this world but will certainly be taken immediately into the next world alive to see Jesus and live with all those who have loved God for all eternity. New bodies and a new earth await all those who submit to God in Jesus the Savior on this earth, humbling themselves before Him to receive His pardon for sin and His gift of righteousness based upon Jesus alone and nothing we have done. Our lives are short-lived. We have been given this time to reconcile with God and work for His glory to earn treasure in heaven. Wasting our lives on our selfish pursuits jeopardizes our souls and diminishes the rewards that could be ours. We need only focus on Jesus. This is our true good. The wise person seeks Jesus through the Scriptures to glorify Him in the world by obeying His commands to love others into the kingdom of God so that he is received warmly and rewarded greatly by the Judge of all people on that day when they meet Him face to face.
