Gary Wilkerson emphasizes the necessity of understanding the significance of the cross in the Christian faith, arguing that true glory comes only from the cross of Jesus Christ. He contrasts the theology of glory, which relies on self-righteousness and human effort, with the theology of the cross, which recognizes our complete dependence on Christ's sacrifice for righteousness. Wilkerson highlights that many people, even in the church, are seeking fulfillment through self-improvement rather than embracing the transformative power of the cross. He calls for a shift from self-reliance to a reliance on Christ's work, urging believers to acknowledge their need for grace and the righteousness that comes through faith alone. Ultimately, he invites the congregation to embrace the cross as the source of true freedom and identity in Christ.
