"Believers are sealed by the Holy Spirt at the moment of salvation. We are sealed unto the day of redemption. Meaning, we cannot unseal anything. It's there, until it is redeemed. By Christ. We are His."
A seal, in Biblical times, was a mark, a sigil, a signature attesting to the truth of a document or other object. It is not a Ziplock baggie presenting an impenetrable barrier between a person and everything else. The translation does not do the intent correctly.
Clearly, the verses being used are there to address fears that someone or something outside can affect our relationship with Christ. Nothing that someone or something else does can affect our relationship with Christ. This is superior to the Moslem faith where e.g., you can lose 'heaven' if you are buried covered in pig offal.
Correct. Nobody can snatch you from God's hand. But you sure can wander away, just like the sheep that Jesus referred to so many times.
Taking verses out-of-context doesn't help believers understand their true standing. Invoking the 'well they weren't really saved anyway' argument doesn't help either. It just turns your argument into a fallacy. Better to face the truth that you can (and some will) lose their salvation by turning away from the truth. Grow up, please.
The OSAS belief has tremendous emotional appeal and the tenacity of this belief over Scriptural evidence to the contrary is evidence of the attractiveness of its appeal.
It appeals mostly to new and immature believers who need someone to tell them what to think and to those who have an interest in occupying that position and 'Lording it over' them, IMO.
