This book, also called the Song of Solomon, is an allegory of the marriage between the Shulammite woman and King Solomon, representing the marriage of the Bride (the Church) and Christ (the King).
This book is tender and intimate and cannot be truly understood by someone who does not have a personal relationship with Jesus Christ. Remember, God created man in His own image and He chose marriage to represent the relationship between himself and the Church. Christians can think of this book as the song sung at their wedding to Christ. All through the New Testament, the Church is called the Bride of Christ (Matt. 9:15; 2 Cor. 11:2; Eph. 5:23; Rev. 19:7; 21:2; 22:17).
The Song of Songs portrays the Bride’s love for the King and her pleasure in His love for her. Then, she dreams of His disappearance and rejoices when He returns–much like the Bride as she awaits the return of Jesus Christ. The King loves His bride and tells her of His devotion. Their love cannot be touched and can never be broken.
That is just a small description, but there is so much more to this book that is rich with truth about the Bride and Christ. He is coming for His Bride one day. Will you rejoice like the Shulammite woman?
