The Holy Spirit Gives Us Joy!
The Holy Spirit gives us joy. And he is joy. Joy is the gift in which all the other gifts are included. It is the expression of happiness, of being in harmony with ourselves, that which can only come from being in harmony with God and with his creation. It belongs to the nature of joy to be radiant; it must communicate itself. The missionary spirit of the Church is none other than the impulse to communicate the joy which has been given.
