There is a common story that surrounds the death of John D. Rockefeller, Sr. If you define life in terms of money, you leave God out of the definition and you end up bankrupt. What counts is your relationship with God. He who denies Me before men shall be denied before the angels of God. This parable tells us how to define life.
Most people define life in terms of material possessions, physical fitness, or the future.
This parable speaks loudly to our generation. What happens when you get some disease which takes away your physical ability. If you define life in these things, you will be devastated. It is interesting that there is a similar parable in the noncanonical Gospel of Thomas. It says, Jesus said, There was a rich man who had much money.
