When the divine origin of marriage is recognized, and the divine pinciples controlling it are obeyed, marriage is indeed a blessing; but when these are disregarded, untold evils are sure to follow.  That which, rightly used, is of greatest blessing, when abused becomes the greatest curse. That's why Jesus spoke strongly against divorce and remarriage.

The marriage relationship is frequently used in the scriptures as a symbol of the relationship existing between God and His people.  Therefore, what God hath joined together, let no man put asunder also let marriage be held in honor among all.

Jesus specifically cites Genesis 2:24 in relation to his condemnation of divorce.  From the very beginning of man, marriage was meant to be permanent, with the two becoming one flesh.  Christ did not only expressly condemned divorce, He also said that any divorce which might possibly take place had no effect whatever on the bond of marriage itself.
