In the Book of Acts, we find that Peter recorded the first events of every major action to be taken by the church throughout the church age. He preached the first sermon, he healed the first sick person, he baptized in the Holy Spirit new converts, he argued in court, he preached to the gentiles first, he changed the rules of acceptance into the church, he raised the dead.
All of this same power is available to every believer, so we must learn how to access it and use it.
