I don't often put "profound" quotes on here, especially from things I've been reading because a) I think it's a bit wanky and, b) all too often the quotes are taken out of context.
But, I was struck by the quote above - cited by John Dickson on his Facebook page - since it, as John pointed out, speaks loudly to the all-too-common attitude of post-modernity.
We don't try.
Not with jobs.
Not with dreams.
Not with church.
Not with faith.
We also don't test.
At least not long enough to reach an informed conclusion.
We give it a half-assed attempt, see that it doesn't instantly cure all our ills or deliver on all it's promises, and then move on to the next new thing.
Someone on the Facebook theme pointed out that this is used apologetically.
While I think this might somewhat fit, I, frankly, don't think that it's identified as a reason for faith's decline.
In order for that to happen, you'd have to be able to stop yourself, consider the culture around you, and have the guts to identify it out loud.
And... most don't have time for that...
