John Piper is the senior pastor at Bethlehem Baptist Church (BBC) in Minneapolis.
He is author of more than a dozen books and has been in the UK speaking at conferences organised by such diverse groups as FIEC, Banner of Truth and the Clarendon Centre.
Piper's life mission statement, adopted by his church, is 'God is most glorified in us when we are most satisfied in him'. With echoes of his hero, Jonathan Edwards, Piper's plea is for a pervasive God-centredness in all of life and worship. He contends that our satisfaction, pleasure and delight is not ultimately at odds with God's design for us. God not only wants us to be holy, but also to be happy.
