This fact, that the opposite of sin is by no means virtue, has been overlooked. The latter is partly a pagan view, which is content with a merely human standard, and which for that very reason does not know what sin is, that all sin is before God. No, the opposite of sin is faith.
Soren KierkegaardThe idea of demonstrating that this unknown something [God] exists, could scarcely suggest itself to Reason. For if God does not exist it would of course be impossible to prove it, and if he does exist it would be folly to attempt it.
Soren KierkegaardWhere unclarity resides, there is temptation, and there it proves only too easily the stronger. Wherever there is ambiguity, wherever there is wavering, there is disobedience down at the bottom.
