I think that people don't know how to do anything anymore. My father was a janitor. He could take a car apart and put it back together. He could build a house in the back yard. Today if you ask people what they know they say 'I know how to hire someone.'
The wisdom of God's Word is quite clear on believers being unequally yoked. And marrying someone who is not a Christian - who is not a daily disciple of Christ - is being unequally yoked regardless of what their beliefs might be.
