The woman said to him, Sir, you have nothing to draw with, and the well is deep: from where then have you that living water?…
I visited two lakes not far apart in a mountainous district of North Wales, namely, Bala and Arenig. Having noticed that one was somewhat muddy and discoloured whilst the other was beautiful and clear, quite transparent down to its bed, where the eye could distinctly see the fishes flitting to and fro, I asked my companion what might be the reason for this difference. He replied, Bala Lake, whose waters are discoloured, is replenished by streams which flow into it, and which bring with them the soft and debris they gather up in their course down the hill-side and through the alluvial earth. But the Arenig, whose water is so beautifully transparent and placid, is supplied by springs bubbling up within its own bosom; hence they bring with them no defiling elements. Herein I found a parable. The motives which are supplied by the world — its pride, its wealth, its fashion, and fame — are corrupt, and as they enter the mind they pollute it. But those supplied by religion, which is a well-spring within, are pure in themselves and purify the whole man.
(A. J. Parry.)
