This maybe the best sermon on why God doesn't want divorce. The two have made a cut covanant vow to God to remain married no matter what. Now we can see adultery is not a reason for divorce but instead an illegal marriage like incestuous, a same sex, or marrying something other than human is the pornia Jesus was referring to. The family is the most important part of church. If Satan gets Christians to believe the vow made between God and husband and wife is not that important then the doctrine of demons is destroying what God has put together.
