When God says in the Bible that natural, unconverted men are dead in trespasses and sins, many people find themselves puzzled. They may respond by saying, “I don’t feel dead, I don’t seem dead. Look at me blink and eat and run and so on.” The problem lies in their failure to recognize that men have both a body and a soul. Their body can be alive and active, while simultaneously their soul can be dead. Then what are the indications that a person’s soul is dead in sin? Well, the easiest thing is to think in terms of the parallel with the body. Those who are spiritually dead cannot see the light of God’s truth.
