How shall I get true knowledge? Knowledge which will be really useful, really worth knowing. Knowledge which I shall know accurately and practically too, so that I can use it in daily life, for myself and others? Knowledge too, which shall be clear knowledge, not warped or coloured by my own fancies, passions, prejudices, but pure and calm and sound; Siccum Lumen, "Dry Light," as the greatest of philosophers called it of old.

To all such who long for light, that by the light they may live, God answers through His only begotten Son: "Ask and ye shall receive, seek and ye shall find."

Westminster Sermons. 1873.
