Barnabas saw the grace of God in action

"When he arrived and saw the grace of God, he rejoiced and encouraged them all to remain faithful to the Lord in firmness of heart,"  (Acts 11:23)

When Barnabas arrived in Antioch, scripture reported that he "saw the grace of God."  What exactly did Barnabas see?  He saw the gifts and fruits of the Holy Spirit in action. The Church of Antioch was a Spirit-filled Church.  What are the gifts and fruits of the Holy Spirit?

"1831 The seven gifts of the Holy Spirit are wisdom, understanding, counsel, fortitude, knowledge, piety, and fear of the Lord. They belong in their fullness to Christ, Son of David. They complete and perfect the virtues of those who receive them. They make the faithful docile in readily obeying divine inspirations.

Let your good spirit lead me on a level path.
For all who are led by the Spirit of God are sons of God . . . If children, then heirs, heirs of God and fellow heirs with Christ."  (Catechism of the Catholic Church #1831)

"1832 The fruits of the Spirit are perfections that the Holy Spirit forms in us as the first fruits of eternal glory. The tradition of the Church lists twelve of them: "charity, joy, peace, patience, kindness, goodness, generosity, gentleness, faithfulness, modesty, self-control, chastity."  (Catechism of the Catholic Church #1832)

Members of a Spirit-filled Church manifest the gifts and fruits of the Holy Spirit as a way of life.  This is what Barnabas experienced when he arrived in Antioch.
