Welcome brother Paul!
I have (and am) learning so much since I've been here. This is a wonderful group of people.
You will find a plethera of KJB resources and information here as well as links to more!
There are also some good KJ defense sermons on sermonaudio.com
I think Samuel Gipp has some there. There may be some older ones too - like from Jack Hyles for instance.
God bless you!
