Once again my aim is to throw out some ideas and stimulate your thoughts on the Song, not to completely convince you of an particular reading of it. Here goes.
When she is asked why she loves him, she replies with wonderful descriptions of him and his love, not will a list of things that he does (see ch5v10-16). He is the object of her affections, he is the the desire of her heart, he overwhelms her. When we think of Jesus, do we merely think of what He has done, or can do, for us? Or do we delight in Him?
Chapters 6-8 seem to speaking eschatalogically speaking of the consummation of the relationship and feasting together. She is "beautiful as the moon, bright as the sun" in 6v10 and like an army. Is this then a clear picture of the church reflecting the Sun and becoming like Him, an vast army collectively displaying the glory Jesus?
There is a wonderful, beautiful and moving verse in chapter 8. Verse 6:
Set me as a seal upon your heart,This love that is stronger than death is great description of divine love. Nothing can separate us from the love of Christ (Romans 8) not even death. The church is sealed by God, kept in His heart, names are written in the Lamb's book of life. This certainly seems to be describing something greater than human romance.
as a seal upon your arm,
for love is strong as death,
jealousy is fierce as the grave.
Its flashes are flashes of fire,
the very flame of the Lord.
A couple of other things that are worth thinking about. Ch2v7 and ch8v4 speak of not trying to stir up love. We cannot manufacture love for Christ with our own efforts. Love comes through a fresh revelation of the grace, goodness and love of Christ. If we are friends of the Bride, we will encourage her to look to Christ, not deflecting her gaze elsewhere. We will see to help our brothers and sister in Christ to captured by a beautiful vision of Him and we will seek to draw others to Him as well, so that His love is known and they may enjoy Him.
