If He is the one who supplies all our needs, and He never runs out of supplies, we can stop thinking about our money in terms of a pie being swiftly eaten up and start thinking of ourselves as conduits of His grace. What He gives to us, we can pass on to others without fear that there won't be enough left over for us.
This expression makes me think about living a life built on Faith and practicing the presence- realizing how important who we are is as a gesture of love and service, what we are- is a gift. Even we don't realize this, let alone many who are absorbed in their worries and irritations.
Also the joy that must be- to at every moment feel guided and protected by the Divine.
