Thanks to a good spot from Strob!
John Piper, author of many books such as ‘Desiring God’, ‘Let the Nations be Glad!’ and ‘Don’t Waste your life’ will be speaking at New Horizon at Coleraine University next summer, from the 22nd to the 28th of July. Piper is unashamedly and joyfully Calvinist which is bound to ruffle a few feathers. He has been labelled a ‘Charismatic Calvinist’ in the past but I think this is basically false (although he is apparently an apple picker). He has also had a few other criticisms which have been answered here if you’re interested.
Anyway, overall I think this is A Good Thing.
