If you recall your greatest treasures, what is on your list?  The things that we think add "value" to our earthly lives, or priceless treasures such as conversations with dear people, memories, family, friends.  Keep focused on the understanding that the only thing that matters is the Life Everlasting, being with God, Jesus, and the Holy Spirit.  And the cost of this treasure, the Kingdom of God, is completely free to us, as Jesus paid the full and complete ("It is Finished") debt for all of us, once and for all.  This Gift of God is yours, paid by the human Jesus on the cross.
