If you want to know what heaven is,
you can spell it in five letters, and when
you put the five letters together they look
like this: J E S U S.

That is heaven. It is all the heaven
the angels round the throne desire to
know. They want nothing better than
this- to see his face, to behold his glory,
and to dwell in it world without end.

(from Spurgeon's sermon, "Christ the
Glory of His People" #826. Luke 2:32.)
