And I will silence in the cities of Judah and in the streets of Jerusalem the voice of mirth and the voice of gladness, the voice of the bridegroom and the voice of the bride, for the land shall become a waste.
Jeremiah 7:34

Marriage doesn't exist for entertainment. It has a purpose. If our peace and prosperity has allowed us the luxury to deny the purpose of marriage, then why should God allow our prosperity to continue?
