Wayne Grudem is one of my living heroes, as unlike many scholars, he has served the church well by writing books that we can all understand, but which are not patronizingly basic. Dr. Grudem is well known as the author of Systematic Theology which in the UK sold almost its entire print run at a Newfrontiers conference. I have interviewed Wayne via email and filmed an interview see parts 1, 2, 3,4, 5, & 6.
As the last of these videos shows, Grudem is no cessationist and he is arguably one of the major causes of the current growth in the reformed charismatic movement.
