Life is short or Life is eternall

Psalm 102:11 “My days are like the evening shadow; I wither away like grass.” Our human nature hates this passage while our God nature loves this passage.  With all the difficulties this short life forces each of us to endure we happily look forward to an eternal time when nothing sad happens and joy is constant.  No heath issues, no conflicts, no unnecessary worries, no disappointments–heaven is almost impossible to imagine.  Given the truth of this passage, how can we do anything other than desire an extremely close relationship with our Savior?
