Psalm 92, Matthew 25, 2 Peter 1

Jack's not talking about recycling or carbon footprint. Psalm 92 says the righteous are full of sap and green. Then he leads us to Jesus' parable of the talents, which is not so much about money, but more about pursuing the knowledge of God (2 Peter 1).  Jack advised us to stop wasting time on things that don't matter, and pursue God.
