The Apostle Paul describes the Christians as carnal in that they are spiritually immature. It does not mean they are not saved. He uses the term “babes in Christ” to denote those who are not growing spiritually but are still spiritual babies. It is sad to see malnourished children who are not growing because of the lack of nutritious food intake. He is using this as an illustration to describe those who cannot accept the instruction that a spiritual man will need.
