And this is one of the most crucial definitions for the whole of Christianity; that the opposite of sin is not virtue but faith. - Søren Kierkegaard

Sin is man's destruction. Only the rust of sin can consume the soul-or eternally destroy it. For here indeed is the remarkable thing from which already that simple wise man of olden time derived a proof of the immortality of the soul, that the sickness of the soul (sin) is not like bodily sickness which kills the body. Sin is not a passage-way which a man has to pass through once, for from it one shall flee; sin is not (like suffering) the instant, but an eternal fall from the eternal, hence it is not ‘once’, and it cannot possibly be that its ‘once’ is no time. No, just as between the rich man in hell and Lazarus in Abraham's bosom there was a yawning gulf fixed, so is there also a yawning distinction between suffering and sin. Let us not confuse it, lest talk about suffering might become less frank-hearted, because it had also sin in mind, and this less frank-hearted talk might be boldly impudent inasmuch as it is talking this way about sin. This precisely is the Christian position, that there is this infinite distinction between evil and evil, as they are confusedly named; this precisely is the Christian characteristic, to talk of temporal sufferings ever more and more frank-heartedly, more triumphantly, more joyfully, because Christianity regarded, sin, and sin only, is destructive.
