Amongst John's individual talks are the excellent The Call to Discipleship from the Discipleship Course, Be Filled with the Spirit from the 'Work Out Your Salvation' series and 4 talks listed on our Conference Workshops pages, entitled 'Liberty As We Worship', 'Reality In The Home', 'Resist the Devil' and 'The Word of Knowledge'. John has recorded scores more studies as well so there is likely to be something on almost any subject you are looking for.
