The Spiritual Life is like this analogy. Our Faith is supposed to be lived out. God pours out his grace on you and it fills you, but it isn’t supposed to stop there. The grace received is meant to flow out of you and into the lives of others. As you allow grace to move from you to others, you are filled with more grace. St John Paul 2nd called this the Law of the Gift – your being increases in the measure you give it away. You find yourself filled evermore with God’s grace, peace, joy etc. as you give it to others.
