Chiefs Running Back Larry Johnson was only 75 yards away from breaking the team record when he was released, all because he couldn't watch his mouth. Following a loss Johnson belittled his head coach and directed a gay slur towards a heckler on twitter. The next day he used the gay slur again towards members of the media in the locker room. Whether we realize it or not words are powerful and should be used wisely.
Ephesians 4:29 says, "Let no corrupt communication proceed out of your mouth but that which is good to the use of edifying, that it may minister grace unto the hearers." In other words watch the foul language. Words should be used to build up others and not tear them down.
Sometimes we may forget God made everyone. So when we call them ignorant, ugly or a gay slur we are talking about God's creation. It cost Larry Johnson his job in Kansas City, it could cost you even more.
