“Lord, send out your Spirit and renew the face of the earth!” We only know that the wind exists because of what it does. A gentle breeze felt on our face or watching a tree swaying or swirling snowflakes all prove the existence of “something” causing these things to happen. But, apart from its effects, we cannot see the origin or substance of wind. The Holy Spirit is the wind of God. Watching an early Church emerge, people coming to believe, disciples of Jesus change the way they live and conduct their affairs-all give witness to the presence of the Holy Spirit. Observing the courage and conviction of those who have found faith, working for justice, feeding the poor, seeing how wounds are healed-all point to something greater than ourselves working and living among us. How do our lives give witness to the Spirit?
