God uses the metaphor throughout the Old Testament that He is like a groom and His people are His bride. When Jesus comes, He uses the same metaphor for Himself, that He is our great Bridegroom. He will give Himself for His bride in order to restore her. The emotions of love and delight, like a bridegroom feels for his bride, is how Jesus feels about us (in a non-sexual way). The words God uses for people are words of intimacy and closeness, we cannot be close when there is sin that separates us. The point is that He has done everything for us and because of what He has done on the cross all our imperfections are not just covered, but REMOVED to where we are an absolute beauty to Him. Why? Because He is that committed to us…that is the good news of the Gospel.
