In chapter 3 we will be looking at how Peter and John had become missionaries in Jerusalem. As we look at the lives of these two men, we notice certain characteristics that will help us in our efforts to be men and women God uses to lead others to Christ. These are the characteristics of a person that God wants to use.
In this study we read how many disciples had gathered back in Jerusalem to wait for the promise of God which was to wait for the Holy Spirit to come upon them. We also read how Peter took it upon himself to start an election process to replace the Judas Iscariot with another disciple in good standing to be the twelfth Apostle as prophesied in Psalms. 
In our first study in the Book of Acts, we talk about the background of the Book of Acts. We discussed the author, the purpose, and the importance of this historical book. We see how this book bridges the gap between the Gospels and the rest of the New Testament. We see how the Book of Acts is about the early church and more importantly, the Acts of Holy Spirit. As we study the Book of Acts, we will be studying how the early church got started and the fundamentals of this Holy Spirit Driven church, so that we can obtain an understanding of what to look for in a church, how to be the church, and the power of the Holy Spirit at work in our lives, as well as in the church today.
