Good morning Father! The grave is six feet deep, covered with dirt and has no value other than a storage place for the deceased. My life is your life and it transcends the grave. However if you would like to invest in only a storage unit, that is your choice. While the cost of storage units are rising the cost of life remains the same through eternity, and has already been paid for in full at the cross. Join the life society. Don't plot for the plot society. Love God!
