For the record, I would not nit pick at most of sozo's views on salvation. However, I think his wrong assumptions on some points lead to wrong conclusions.
I do not know if paulpeterson was genuinely saved or not when he was young (I received Christ when I was 12, but lived far from Him until I was 18. His conviction led to radical transformation, and I was born again again in a sense. I think I would not have gone to heaven when I was 17).
I do not believe in unconditional eternal security. I believe in conditional, biblical, eternal security: a believer is secure, but this does not preclude the possibility of falling away or apostasizing, forfeiting a relationship with God and the promise of life. I think sozo reduces salvation to the possession of life and divorces it from the need to continue in right relationship with the person of Christ. I John says that life is in the Son, not inherent in us. If someone rejects the Son, whether they once believed or not, they are no longer walking in life, but have returned to death and darkness.
paulpeterson is not a believer now. He may or may not have been as a child (quite possibly he had mere head knowledge and never was 'born again'). OSAS is simply not biblical. He is another one of many who illustrates the stern warnings in Scripture about the possibility of apostasy and the need to persevere.
Heb. 10:35 ff. "So do not throw away your confidence (possible to do so); it will be richly rewarded. You need to persevere so that when you have done the will of God (love and trust Him and continue to do so), you will receive what He has promised (abundant and eternal life)....but we (those who continue to believe vs fall away due to persecution or temptation) are not of those who shrink back and are destroyed (some did), but of those who believe (and continue to believe...Greek present, continuous, habitual tense) and are saved (believers are glorified in the end...unbelievers are condemned, whether they once believed or not).
