What does the Bible say about the church's beauty in Christ?

In the Book of Song of Solomon, particularly in chapter 6, the church is depicted as beautiful and powerful, described metaphorically as 'fair as the moon' and 'clear as the sun,' embodying the glory of a profound relationship with Christ. This beauty is further illustrated as 'terrible as an army with banners,' emphasizing the strength and unity of the church in Christ. The imagery reveals that the church is God's chosen vessel, demonstrating His love and grace to the world, and serves as a witness to Christ's eternal love, which transcends all understanding.
