When I say that I am convinced of these things I speak with too much pride. Far off, like a perfect pearl, one can see the city of God. It is so wonderful that it seems as if a child could reach it in a summer's day. And so a child could. But with me and such as me it is different. One can realise a thing in a single moment, but one loses it in the long hours that follow with leaden feet. It is so difficult to keep 'heights that the soul is competent to gain.' We think in eternity, but we move slowly through time; and how slowly time goes with us who lie in prison I need not tell again, nor of the weariness and despair that creep back into one's cell, and into the cell of one's heart, with such strange insistence that one has, as it were, to garnish and sweep one's house for their coming, as for an unwelcome guest, or a bitter master, or a slave whose slave it is one's chance or choice to be.
