we learn that the disciples were together in continual devoted prayer until the Holy Spirit came down. Prayer is prerequisite to revival!! We need to devote ourselves to prayer so that we can continue to be filled with the Holy Spirit. The power of God has come to make us witnesses. He wants us to experience God's power as described in Luke 4:18 we preach the Gospel, heal the brokenhearted, set the captives free, Amen!!!
