"Christ's presence hath my prison turn'd A blessed heaven; what then will In heaven hereafter, when it now creates Heav'n in a dungeon; goals to courts translates?' 'He is not bound whom Christ makes Though shut close prisoner, chained, remains A godly man's at large in every place, Still cheerful, well content, in blessed Unconquered; he a sacred heaven still About within his breast."

John Bunyan

Bunyan spent 9 years in prison.
