Sin does not come unawares upon a man: God is just, and would never punish a man, as He always does, for being overcome by sin if sin were able to take him unawares; and neither sleep nor old age always come unawares upon a man.
People frequently feel themselves going to sleep and feel old age stealing upon them; though there can be no doubt that sleep and old age sometimes come unawares--old age came unawares upon me; it was only the other day that I was aware that I was old, though I had long been old, and sleep came unawares upon me in that chair in which I had sat down without the slightest thought of sleeping.

And there as I sat I had a dream--what did I dream about?
the sermon, musing upon which I had been overcome by sleep?
not a bit! I dreamt about a widely-different matter.
Methought I was in Llangollen fair in the place where the pigs were sold, in the midst of Welsh drovers, immense hogs and immense men whom I took to be the gents of Wolverhampton.

What huge fellows they were! almost as huge as the hogs for which they higgled; the generality of them dressed in brown sporting coats, drab breeches, yellow-topped boots, splashed all over with mud, and with low-crowned broad-brimmed hats.

One enormous fellow particularly caught my notice.

I guessed he must have weighed eleven score, he had a half-ruddy, half-tallowy face, brown hair, and rather thin whiskers.
