Question:
What are some of the ‘bad foods,’ or bad things that hinder our growth as Christians?

Answer:
One thing that hinders our growth is to be yoked together with unbelievers, and the Bible tells us not to do this. “Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?” (2 Corinthians 6:14).

An example of an equal yoke would be two oxen yoked together to plow a field. An unequal yoke would be if an ox and a donkey were yoked together to plow the field. It would be impossible to do the job right with this yoke because the ox and donkey are not equal. They are not the same in strength, abilities, or temperament, for they have different natures. The same thing is true if a believer and an unbeliever would be yoked in a common purpose such as religion, marriage, business, etc. They could not do the job well, and furthermore God tells the believer not be yoked with an unbeliever.It is important also to realize that if two believers are yoked together in marriage, etc., they each must fix their concentration or focus on the Lord and seek to please Him or they will have problems accomplishing what they are trying to do together. The way a farmer plows straight furrows in a field is that he picks out an object on the other side of the field, and keeps his eye on that goal. Likewise the believer must “set” his “affection [or mind] on things above, not on things on the earth” (Colossians 3:2), if he is going to accomplish what God wants him to accomplish.
