A selection from a letter by Thomas Charles, to Mr. and Mrs. John Walker, of Chester, England (no date):
I am glad that it is my employment through life to speak of Him to helpless sinners. I am glad that others can speak better of Him than I can. But He is infinitely beyond what any of us can think or speak; and we ought to be ashamed of ourselves when we speak with the most light and warmth of Him. The more we know of Him, the less we shall think of our knowledge of Him, and the more we shall long to grow in the knowledge of Him.
