Eternal security is a careless doctrine. From God's point of view, He offers it eternally. However, to say we can never lose our salvation is nonsense. Why so many warnings in the NT? The major cop-out is "well, he was never really saved in the first place". Oh,, no? Well, then who will he pray to next time? That "plucking out of the hand" scriptures says noting about someone walking out and away from God of their own free will. Do you really believe the Bible teaches that once you get saved, you can't decide to walk away, later? I had an atheist tell me he was a devoted Christian for a lot of years and he just decided it wasn't real and walked away. So, you say he wasn't saved in the first place? That is careless and presumptuous.

For every Scripture you produce to prove eternal security, I can find one that counters it.
