The prayers of the early believers had the power to physically shake buildings and the power to open the doors of their prison. It serves not only as power to boldly engage the world for Jesus, but also a power that protects us from the schemes of the enemy. It serves as a testimony to the power of God to change lives and a reminder that His power comes from His being the author of all creation. The power we derive from prayer is a source of strength for us in our everyday life. It is a power that is unleashed through the Holy Spirit, and one that is available to us for the asking.
