John R.W. Stott, 27 April 1921 – 27 July 2011

"The Christian landscape is strewn with the wreckage of
derelict, half-built towers -- the ruins of those who began
to build and were unable to finish.  For thousands of
people still ignore Christ's warning and undertake to
follow him without first pausing to reflect on the cost of
doing so.  The result is the great scandal of Christendom
today, so-called 'nominal Christianity'."

--John R.W. Stott, from "Basic Christianity" (rev. edn. London: IVP, 1971),
p. 108.
