Why do you spend money for that which is not bread, and your labor for that which does not satisfy?
~ Isaiah 55:2
Once God has become a living reality for us, we simply have to love others. We cannot do otherwise. And once we live in love, we are moved quite naturally and joyfully to serve others. God is love and if we live in union with God, we have the strength and longing to love others. Service is a spiritual activity, the natural fruit of love.
