Spurgeon's Sermons Volume 30: 1884

THOSE who boast of their knowledge betray their ignorance. Knowledge is
not a possession to be proud of, since it brings with it so great a
responsibility that a nurse might as well be proud of watching over a
life in peril. Knowledge may become good or ill according to the use
which is made of it. If men know God, for instance, and then glorify
him as God, and are thankful, their knowledge has become the means of
great blessing to them; but if they know God, and fail to glorify him,
their knowledge turns to their condemnation.
