We begin to notice, besides our particular sinful acts, our sinfulness; begin to be alarmed not only about what we do,
but about what we are.
This may sound rather difficult, so I will try to make it clear from my own case.
When I come /to my evening prayers and try to reckon up the sins of the day,
[nine times out of ten the most obvious one] is some sin against charity;
I have sulked or snapped or sneered or snubbed or stormed.
And [the excuse //that immediately springs /to my mind] is that the provocation was so sudden and unexpected;
I was caught off my guard, I had not time to collect myself.
Now that may be an extenuating circumstance /as regards those particular acts:
they would obviously be worse /if they had been deliberate and premeditated.
On the other hand, surely [what a man does /when he is taken off his guard] is the best evidence /for what sort of a man he is?
Surely [what pops out before the man has time to put on a disguise] is the truth?
If there are rats in a cellar you are most likely to see them if you go in very suddenly.
But the suddenness does not create the rats: it only prevents them /from hiding.
In the same way the suddenness of the provocation does not make me an ill-tempered man;
it only shows [me] [what an ill-tempered man I am].
The rats are always there in the cellar,
but if you go in /shouting and noisily they will have taken cover /before you switch on the light.
