David Wilkerson emphasizes God's vision for the last-day church, which is to be a powerful, Spirit-filled body that fully preaches the gospel with signs and wonders following. He critiques the current state of many churches, which he believes have become complacent and devoid of the Holy Spirit, focusing instead on worldly matters. Wilkerson calls for a remnant of believers who will turn away from the deadness of modern religion and embrace a life of holiness and supernatural power. He envisions a church that not only preaches the gospel but also demonstrates its truth through miraculous works, urging believers to prepare their hearts for God's greater purpose. Ultimately, he believes that God is raising up a humble yet powerful army of believers who will impact their communities and the world.
