More proof-texting!!
The son shall not bear the punishment for the father's iniquity.
You have avoided the context which is capital punishment or civil law.
It has nothing to do with spiritual death or salvation.
If a son has a wicked father, why should his father's wicked reputation and sinfulness fall upon the son? It wasn't his fault. The son shall not bear any punishment for his father's wrong-doings. He is innocent from them. Go and read the context. It has nothing to do with salvation or spiritual death. It is civil law speaking of capital punishment. You have misapplied Scripture.
No DHK, we have been over this, this speaks of a man dying "in his sin" which speaks of eternal damnation.
Eze 18:18 As for his father, because he cruelly oppressed, spoiled his brother by violence, and did that which is not good among his people, lo, even he shall die in his iniquity.
Eze 18:21 But if the wicked will turn from all his sins that he hath committed, and keep all my statutes, and do that which is lawful and right, he shall surely live, he shall not die.
22 All his transgressions that he hath committed, they shall not be mentioned unto him: in his righteousness that he hath done he shall live.
23 Have I any pleasure at all that the wicked should die? saith the Lord GOD: and not that he should return from his ways, and live?
24 But when the righteous turneth away from his righteousness, and committeth iniquity, and doeth according to all the abominations that the wicked man doeth, shall he live? All his righteousness that he hath done shall not be mentioned: in his trespass that he hath trespassed, and in his sin that he hath sinned, in them shall he die.
These verses are not speaking of civil penalties, they are speaking of a man dying "in his sin" as Jesus spoke of in John 8:
Jhn 8:24 I said therefore unto you, that ye shall die in your sins: for if ye believe not that I am he, ye shall die in your sins.
However, these verses do not support the idea that a man can lose salvation. Eze 18:21 shows that if a man repents and trusts in God that his sins will be forgiven, and "in his righteousness" he will live. We are clearly told that righteousness is only imputed to those who believe in Romans chapter 4.
As for Eze 18:24, all men are born upright, and all men turn from their righteousness and will die in their sins unless they trust in the Lord.
