David Wilkerson emphasizes the urgent need for a powerful outpouring of the Holy Spirit among God's people, akin to the events of Pentecost. He draws parallels between the cries of the faithful in Isaiah's time and the disciples in the Upper Room, both seeking God's presence and intervention in a world filled with darkness. Wilkerson encourages believers to unite in prayer, asking God to rend the heavens and come down, as they hold onto the promise of His coming. He reminds the congregation that God is actively listening to their cries and is preparing to manifest His presence in response to their faith. The sermon calls for a collective awakening and readiness to meet Jesus as He returns.
