After Paul encourages us to seek things that are above and set our affections on God and His desires, he turns to the negative. There are some people who do not like negative. There are some preachers who will never preach against sin, or on the doctrine of hell. They choose to focus only on the positive. Why? Because it makes people feel good. It is easier to draw a crowd with positive things. Yet, if we are going to be truthful to the Word of God, we must also focus on the negative things.
