This sermon explores the theological contrast between Babylon and the New Jerusalem, defining the believer's true identity as the bride of Christ rather than a product of past sin or failure. It emphasizes that while believers are already new creations in Christ, the process of sanctification continues through life's trials, which God uses to conform them to the image of Jesus. Drawing on Revelation 21 and 1 Peter 2, the message presents the church as living stones being built into a spiritual house, with Christ as the cornerstone. The preacher encourages the congregation to reject self-defined identities rooted in guilt and to embrace the secure, holy status granted by the gospel. Ultimately, the sermon points to the future hope of perfection and eternal dwelling with God in the New Jerusalem.
