The book of acts is not a chronological narration. You will see that every story is told like each event is the logical continuation of the other, but in fact there are significant amount of time on between each episode narrated.
These seven chapters talks about many different situations that the early church faced during its first years as the witness of the risen Christ. I am glad that the writer told his story from a very open perspective, in which we find the awesome development and great accomplishments of the church, but also its mistakes, crisis and sins.
The story of Ananias and Sapphira (5: 1-1) is one the most challenging events that Luke shares in his book. It is amazing that among miracles, wonders and signs, we also can find punishment and discipline. Also in chapter 6 we will find another difficult situation that can touch us powerfully. It is the story of the daily distribution of the food. God was moving his power among the church in a mighty way, but still the church was having trouble with prejudice and preferences.
Then comes chapter 7-9 which the transitional passage that will bring Apostle Paul into the spotlight, and also will show us how the Gospel was extended to the gentiles. Stephen is another great story of courage and commitment, that remind us that living for Jesus could also represents dying for him. Remember he called us to be witness, and the meaning of witness also implies the ability to probe with our death if necessary that Jesus is the messiah.
Chapter 9: 1-31 is the great event of God transforming Saul of Tarsus one of his fiercest enemies into one of most faithful witness. Then, will move forward to the expansion of the church into the gentile world from chapter 10-12. The new faith is overwhelming contagious, and many people are brought to God because of the transparence, manifested power of God and fraternal environment that the church practice and experience.
This new faith is not always a triumphal one. They undergo a lot suffering and opposition, but they learned to trust the Lord and experienced great deliverance and blessings in their journey.
Keep reading and learning, but never forget we are part of that wonderful, suffering and victorious church too.
