Reading these verses you immediately notice that Paul makes a distinction between three types of people. In v2:14 he talks about the natural man. In v2:15-16 he talks about the spiritual man. Then in v3:1-4 he talks about the carnal man. What we see in these verses are different spiritual stages that a human beings can go through. All people start off as natural. Those who trust in Christ as their Lord and Savior receive the Holy Spirit and then become spiritual. Unfortunately many Christians allow their sinful nature to take control in their lives and they go from being spiritual to being carnal. Everyone in here will fall into one of these three categories. In fact, that is the central truth we need to know. Right now, I am a natural, spiritual, or a carnal person. The question each one of us needs to answer is, who am I?
