Acts 1

"But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."  (vs 8)

This verse essentially gives us the structural outline of the Book of Acts:

• Chp 1-7  - The Church in Jerusalem (Jews)
• Chp 8-12 - The Church in Judea and Samaria (Transition)
• Chp 13-28 - The Church in the ends of the known world at the time (Gentiles)

While Chp 1-12 primarily narrates Peter's ministry, Paul's ministry to the Gentiles is the focus Chp 13-28.  In the Book of Acts, we will see the transformation of a group of frightened Christians in the Gospels after the Crucifixion, into Leaders of the Early Church, being models of courage and faith, spreading the flame of the Holy Spirit to the world.

Through the use of Scriptural quotes, Peter pointed out that everything that has happened was a fulfillment of prophesy, including the betrayal of Judas.   In this passage, we see that the leadership of the Early Church were formed by Apostles, chosen by Christ; witnesses to Christ's ministry, Resurrection, and Ascension; taught authoritative truths, given the mission of being His witnesses, and were people of prayer.
