Can you marry someone hoping to change them later?

Les teaches that people often think of an unequal marriage only in terms of marriage itself, but the principle extends to anything where people must work together for a common cause. As soon as an unbeliever and a believer are put together, they are just as unequally yoked as an ox with a donkey or as a garment made of linen and wool. Les says he is not a marriage counselor or a pastor, yet many people call him with marital problems, and invariably the problem was being unequally yoked one way or another. Their problems began before they ever got married. He recalls asking a young lady whose husband had become a wife beater whether she knew he had that potential when they were going together. She admitted maybe a little. When asked why she married him, she said he was the star football player. Les notes he has nothing against football players, and a football player can be a good husband, but choosing a man just because he is a star football player is as ridiculous as it gets, and it is another unequal yoke. People walk into problems with their eyes wide open, thinking they can change the person somewhere down the road, but people do not change.
