I have known several people who say they or someone they know only thought they were saved, but then realized they weren't and "accepted Jesus into their hearts". I do not understand this thinking. I suppose if you "think" you're saved just because you were baptized there would be some legitimate doubt, but in the case where the person had faith, believed, and showed fruit, believing they were saved, and then years later "received" Christ because they weren't really saved, I don't have clue what this means. If we can "think" we're saved, but in reality we're not, how can anyone possibly have any assurance? I hope I made sense because as I read this back to myself it sounds goofy.
