G. Campbell Morgan emphasizes the significance of Pentecost as the moment when the Holy Spirit was poured out on the disciples, transforming them from mere followers of Christ into a unified Church empowered for ministry. He highlights that the disciples were instructed to wait for the Spirit before beginning their mission, and that the coming of the Spirit marked the initiation of a new era in God's plan, creating a new Temple of praise, prayer, and prophecy. Morgan notes that this event was not a result of human merit or prayer but a divine gift, establishing the Church as a living entity filled with the Spirit's power to reach the world.
