There are two advantages in this. First, it is clear that anything white looks very much whiter against something black, just as the black looks blacker against the white. Secondly, if we turn from self towards God, our understanding and our will become nobler and readier to embrace all that is good: if we never rise above the slough of our own miseries we do ourselves a great disservice. We were saying just now how black and noisome are the streams that flow from souls in mortal sin. Similarly, although this is not the same thing -- God forbid! It is only a comparison -- so long as we are buried in the wretchedness of our earthly nature these streams of ours will never disengage themselves from the slough of cowardice, pusillanimity and fear. We shall always be glancing around and saying: "Are people looking at me or not?" "If I take a certain path shall I come to any harm?" "Dare I begin such and such a task?" "Is it pride that is impelling me to do so?" "Can anyone as wretched as I engage in so lofty an exercise as prayer?" "Will people think better of me if I refrain from following the crowd?" "For extremes are not good," they say, "even in virtue; and I am such a sinner that if I were to fail I should only have farther to fall; perhaps I shall make no progress and in that case I shall only be doing good people harm; anyway, a person like myself has no need to make herself singular."
