What does the Bible say about the church's significance?

In Isaiah 62, the church is depicted as Zion, the Bride of the Lord Jesus Christ, which God has eternally loved. It may appear small and insignificant in the eyes of the world, but God has preserved a remnant of His people throughout history. This remnant is important because it showcases God's glory and His sovereign grace in electing and calling a people for Himself. The church is described as a crown of glory in the hand of the Lord, emphasizing its precious status in God's eyes, regardless of worldly perceptions.
