How do we know the church is perfect and ideal?

The perfection of the church stems from its divine origin as it is established and sustained by God Himself. In the sermon, it is noted that while present manifestations of the church may be flawed due to human involvement, the church as conceived by God is always seen as perfect and ideal. This distinction is crucial as the church is viewed as the bride of Christ, set apart for Him and ultimately fulfilled in the New Jerusalem. Therefore, believers can take comfort in knowing that God's plan for His church, despite present imperfections, guarantees its ultimate perfection in eternity.
