Today we're learning that the laws of marriage and divorce are really pointing spiritually to God divorcing the nation of Israel as well as the corporate church for fornication. This is why God instituted this law in Deuteronomy 24:1. From the vintage point of a corporate body, God does divorce for fornication. However from the vintage point of His elect sinning (spiritual fornication) there is to be no divorce. Nothing can separate them from the love of God. From our perspective as believers, we should live out the moral law in our own lives. We should always be willing to forgive even for fornication just as Christ forgives His people for spiritual fornication after salvation.

• The wife is bound by the law as long as her husband liveth; but if her husband be dead, she is at liberty to be married to whom she will; only in the Lord. Corinthians 7:39
