The ever renewed mission of the Spirt to the soul that is in the grace of Christ is to be understood by the analogy of the natural breath that keeps renewing, from moment to moment, our bodily life. The mystery of the Spirit is the mystery of selfless love, and we give Him to others in the outgoing of our own charity. Our life in Christ is then a life both of receiving and of giving . We receive from God, in the Spirit, and in the same Spirit we return our love to God through our brothers.
