179. Each person has an internal and an external man. The internal man is what is called the spiritual man, the external the natural man. Both of these have to be regenerated for a person to be regenerated. In the case of someone who is not regenerated, the external or natural man is the master, and the internal is the servant. But in the case of someone who is regenerated, the internal or spiritual man is the master, and the external is the servant. This shows clearly that from birth one has the correct order of life turned upside down; thus what ought to be master is servant, and what ought to be servant is master. For a person to be saved that order has to be reversed and the only way this reversal can happen is by being regenerated by the Lord.
