No one is arguing that this is physical death. We are saying that a man's spirit is dead. Only God can make a man's spirit become alive.This is what Paul says, "And you were dead in your trespasses and sins," Eph. 2:1
Were they actually not breathing, lifeless, dead as a door nail bodies??? No! They were spiritually dead. Physically they were alive, spiritually they were dead to God.
It has been several posters on here, you included, who have said we can use characteristics of a physically dead corpse to describe what Paul means here, thus applying an analogy. Paul CLEARLY says what this "Dead" means in this chapter...
"without God, having no hope"
"having the wrath of God abiding on us"
"Alienated from the promises of God"
"enemies of God"
There are some here who have went above Scripture and have ascribed characteristics of being "dead" that Scripture does not actually speak on.
Paul is literally talking about the human spirit in Ephesians 2:1.
Now, please show where Paul is making an analogy or allegory in this passage. So far you have avoided the issue.
