Let’s start by getting this first idea straight: God saves us, by his grace. It’s entirely his work, done by his power; we don’t save ourselves; we can’t possibly. No number of good deeds, no amount of good karma, not even memorizing all the right doctrines, is gonna do it. We gotta entirely entrust our salvation to God. Period. Full stop.
Since we can’t and don’t save ourselves, various Christians figure an attached idea—and they insist it’s a necessary attached idea—follows: We can’t and don’t un-save ourselves. If God saves us, the only way we can get unsaved is if God does it—and he’s not gonna. He’s chosen us, he’s elected us, for salvation. And it’s permanent. It’s a done deal. Nothing in our universe can separate ’em from God’s love. Ro 8.39
Not even if they themselves later choose to quit Jesus. (So how do they explain ex-Christians? “Oh, they were never really Christian.” Which opens up a whole different can of worms… which I’ll get to tomorrow.)
Sometimes Christians call this idea perseverance of the saints, or “perseverance” for short. Sometimes eternal security or absolute security. Sometimes assurance, though other Christians (like myself) mean something very different by this term. More recently some Christians have adopted the term free grace. All these terms mean “once saved, always saved”—OSAS for short, but since I really don’t like acronyms I’m going with “always saved.”
And loads of Christians have adopted the “always saved” view. It tends to get associated with Calvinists, but they’re far from the only Christians who believe it. Legalists don’t, ’cause they love being able to threaten people with hell; Pelagians don’t, ’cause they think God saves them based on karma, and bad karma earns you hell. But the rest of Christendom tends to think, “Well yeah, we don’t save ourselves… so it stands to reason we can’t unsave ourselves, so I guess it is a done deal.” The only reason they’d consider an alternative view, is if they know any ex-Christians and can’t rationalize ’em away as “weren’t real Christians before they quit.” Or, of course, if they grew up among legalists and Pelagians.
I grew up among both, but that’s actually not why I reject the always-saved view. Because I used to have the always-saved view. I totally get its appeal: It’s the security. It’s awesome that we can never just lose our salvation—that if we have one bad day, or commit a particularly heinous sin, God’s not gonna say, “That’s it! I’m done with you” and now we’re damned; our sins have driven God away. God loves us far too much to give up on us entirely. It’s a wonderful idea.
But “always saved” takes this idea to an extreme that can’t be supported by the scriptures. Because, as I say in all these articles on apostasy, the bible’s authors warn us to not reject God and his salvation; and it makes no sense that these passages would be in there if it’s impossible to unsave ourselves. Only God can save us, true. But we can still totally reject his salvation.
