The Book of Acts is the writing in the Bible (or accumulated Scriptures accepted by most Christian denominations) that is a continuation of Luke's Gospel, but appears after the Gospel of Saint John. Gospel means "good news." The Acts of the Apostles is the story of the disciples of Jesus Christ after His death and resurrection.

The coming of the Holy Spirit as a baptizer, and the Apostleship of Saul (now Saint Paul} of Tarsus are the main elements in this chronology.

Here we are introduced to the first Christian martyr, Saint Stephen. He was ordained as one of the first deacons (usher|/waiters]) of the church, but wound up preaching the whole history of Isreal, up to the present situation of his audience's guilt in crucifying his Lord Jesus, and wound up stoned to death.

Pentecostal, and charismatic Churches use the "Day of Pentecost" in this book as proof text for the same Holy Spirit Baptizing today, with its evidence of speaking in tongues.

The journeys of the Apostle Paul, being beaten, shipwrecked and jailed almost rivals those of another ancient written about in Greek, Ulysses.
