Acts chapter 4 follows the miracle healing by Peter of the man crippled from birth. After Peter and John are arrested, they are released and return to the disciples and tell them what great things God has done.
This inspires the new believers to pray all night for the same boldness Peter and John had. In the night the Holy Spirit is poured out on them. They go out and share with unbelievers that Jesus is the Christ, the Savior of the world.
We need to do this today. If we are not reproducing disciples, we are dying. Instead, we should die to self and go in the power of the Holy Spirit to plant seeds of life.
The Moravians held a prayer meeting for a hundred straight years, 24/7. The fruit of that was a world wide mission outreach. Impossible, but in Christ and the Holy Spirit they did it. Their call to go to unbelievers is an amazing story: "That the Lamb who was be slain may receive the reward of His suffering."
They even sold themselves into slavery to reach unbelievers with Jesus!
