Today's gospel ends by reminding us of something that not just Catholics but all Christians tend to forget.
Without cost you have received; without cost you are to give.
We do not buy our salvation. We do not earn our salvation. It comes through grace. The Catechism defines grace by saying:
Grace is favor, the free and undeserved help that God gives us to respond to his call to become children of God, adoptive sons, partakers of the divine nature and of eternal life.
Free and undeserved help. Imagine for a moment if we were to begin truly imitating God whose children we are and in whose image we are made. Imagine if for the year of mercy we were to start handing out free and undeserved help.
