Pastor John Piper, author Desiring God; Meditations of a Christian Hedonist (1986), has been invited to be the keynote speaker at the London Men’s Convention planned for June 2018. Rev. Richard Coekin, Director of the Co-Mission group of churches in south London, has recently announced his invitation to John Piper. Coekin demonstrated his lack of spiritual discernment when he invited Mark Driscoll to speak at the London Men’s Convention in 2011.
