“After Peter and John had been set free they went to their fellowship and told them what the chief priests and the Jewish elders had said to them. All who heard their story were moved, and in one mind prayed together…When they had finished, the place where they were together was shaken. They were all filled with the Holy Spirit, and began to tell God’s message fearlessly.” Acts 4:23-24, 31 (paraphrase)
Peter and John were arrested by the Jewish religious leaders. God had done a miracle through them in healing a lame man. All the people who saw were amazed and were eager to know how this could happen. Peter and John went on to preach Jesus Christ, who not only has the power to heal but to save. They were arrested for preaching Jesus Christ. Finding no way to keep them or punish them due to the public miracle they let them go.
After hearing the story the people, having one mind, began to pray. They praised God for his works, they prayed the Scriptures, they prayed about their situation, and they prayed for boldness to preach the message of the gospel, and the power to heal with signs and wonders.
We read the books of Acts in one of two ways. Either we read the book of Acts as history seeing all that God had done in the past through the apostles and disciples. We see all that happened as being in the past and “not for today.” The book of Acts is only information about what happened and not a mirror to compare our lives, or our churches, to. As a consequence, many churches remain dead and powerless.
Another way we read the book of Acts is with a longing for God to work like he did before. We sit in our pews and wonder why God is not moving like he did in the book of Acts. Why people aren’t being saved. Why we see no miracles, signs and wonders. Why we remain in disunity, faithless, and powerless. Why are our churches empty. The consequence of being “pew sitters” is the same as reading the book of Acts as history: dead and powerless churches.
Our acts don’t match the acts of the disciples in the book of Acts.
Peyton Jones said, “If we want to witness kingdom expansion like the apostles did, it’s not enough to know what they knew. We need to do what they did.” 
From our passage today we see a glimpse of what the disciples of the early Church did: they prayed.
Not just any type of praying, but, praying together in unity. The Scripture says, “they lifted their voices together to God…” (ESV). They prayed with one heart, one focus, and one mission. They wanted the power of God in their church, not for protection, but for power and boldness to preach the gospel of Jesus Christ. This is the act, the first act, any church, or group of churches, should take in winning their community to God.
When the Church comes together in unity there is power in our prayer. Jesus promises his presence, especially when we are gathered together in his name. And when we pray as one, we shake the community, and we become bold to speak his message fearlessly.
