Kenneth Perkins, one who has corresponded with me through e-mail, commented with much wisdom that, “ the idea of Eternal Security is that I should be able to know now that if I were to die I would be saved. This, however, is not the case; Jesus says that many will call Him "Lord" but not make it into the Kingdom. Second, if OSAS is true and those people who abandon the Church were never saved in the first place, how can we be confident that we are saved? Is it not possible that we are not truly saved since those other people were not truly saved even though they believed themselves to be? The OSAS position itself begs the question it is supposed to be able to answer: "How can we know that we're saved?" If we can't know until we've died and not renounced Jesus, how can I be sure now that I am saved? I think I am, but so did the apostates who left (who many who hold to OSAS believe were never saved). If the answer is that some people have left that were Bible-believing Christians, then how is Eternal Security true?”
