The passage in Ezekiel 18 is not speaking of eternal life, but rather temporal life. Take for example vs. 24, "in them (iniquity) shall he die". In other words, the man who commits iniquity will die according to the Mosaic law (vs. 26), "for his iniquity that he hath done shall he die" is the same thing. So this passage has nothing to do with losing one's salvation, it has to do with the wicked losing his temporal life in accordance with the Mosaic law. Now let's deal with the Hebrew word translated "righteous" in this passage. It doesn't mean saved, it means doing things correctly or right. An example can be found in 1 Sam. 24:17, "Thou art more righteous than I...". A person is either saved or not, he is not more saved than another. Note also 1 Kings 2:32, "...2 men more righteous and better....". "Righteous" is not saved, it is the description of having done what is right and good.

There's no way of knowing if that man was a believer (i.e. saved) or not. But if he was he would die, but then he would be resurrected unto eternal salvation. But this passage has nothing to do with eternal life, it is speaking of the wicked losing his temporal life. Hope this helps! If you are so confident in the NOSAS doctrine, then why not take it to the arena?
