Treasures here on earth won’t last.  They weren’t made to last.  Several years ago my childhood home burned down and was almost a total loss. Many things that had great emotional value were lost in the fire. Those treasures are gone forever.  But the treasure we have in Christ can never be taken away from us.
9 “Don’t store up treasures here on earth where they can erode away or may be stolen. 20 Store them in heaven where they will never lose their value and are safe from thieves. 21 If your profits (treasures) are in heaven, your heart will be there too. “
