I have always loved the Acts of the Apostles and have often recommended it to those who are approaching the Bible for the first time. Filled with colorful narratives, adventure, martyrdom, persecution, journeys by sea, etc., it makes for stimulating reading indeed.
But I love it especially because it shows us the excitement of being a follower of Jesus. Long before there were parishes and dioceses and the Vatican and other institutional structures, there was this band of brothers and sisters who were so overwhelmed and energized by the fact of the resurrection that they went careening around the world and to their deaths with the message of Jesus.
