Mammon does not mean money

The word mammon means the treasure  that a person
believes in.  It doesn't have to be material.  It can even
mean abstract "things" like hope, love, time, goals, these are
things that people treasure.  They can lead one away from
love of God so they can be considered mammon.
Look at your investment in any thing at all.
Your marriage, your friendship, your talent, anything.
What will happen to you if that which you treasure
proves false?  If you would be devastated then that
in which you have invested is mammon.
Matthew 6:24
