Culture is an unseen force that causes us to become like the people we spend a lot of time with. Every family and organization has its own unique culture. The head of the family or leader of an organization plays an important role because members naturally follow his queue about what is appropriate and inappropriate behavior. That is why Christians need to be careful about who they associate with and what organizations they belong to.
Solomon stated in Proverbs 27, “Iron sharpeneth iron, so a man sharpeneth the countenance of his friend” and “as in water face answereth to face, so the heart of man to man” (Proverbs 27:17,19). In other words, we are a reflection of those around us. If you want to know what you are really like, take a close look at your friends.
