Song of Solomon 4:7 Thou art all fair, my love; there is no spot in thee.
I think this verse is referring to the bride. She is beautiful. She has no spot or blemish. We know that is because of the Lord Jesus Christ and what He has done through His blood on the cross. We stand before God without sin or stain of sin. We are all fair and beautiful. Not because of something we have done but because of His grace.
