In American fiction, belief is like that. Belief as upbringing, belief as social fact, belief as a species of American weirdness: our literary fiction has all of these things. All that is missing is the believer.
What modernity requires is not that you cease living according to your faith, but that you accept that others may differ and that therefore politics requires a form of discourse that is reasonable and accessible to believer and non-believer alike. This religious restraint in politics is critical to the maintenance of liberal democracy.
The believer is sensible of his infirmities, for it is supposed that he is wrestling under them. He sees, he feels, that he is not man enough for his work; that his own hands are not sufficient for him, nor his own back for his burden; this is what drives him out of himself to the grace that is in Christ Jesus. And thus he lies open to the help of the Spirit, while proud nature in unbelievers is left helpless.
I'm a firm believer in quiet confidence. By that I mean knowing inwardly that you are good, and not exhibiting a boastful attitude outwardly. If an athlete doesn't believe in himself, no one else will.
Having friends around for a pleasant evening is one of life's most cherished joys as far as I am concerned. But when those with me are fellow believers, how much greater that joy is, for we know that it's rekindled, one day in eternity.
