There is a lot of confusion about the doctrine of the Kingdom of God and the Gospel of the Kingdom. I think if we would study Symington's work a bit more we would benefit from it.
A Journalist J. K. Wall from here in Indianapolis has done a good work in bringing this work down to better level of understanding. I read some of it before it was published and have some criticism but this is an important work and very good. Anytime you update and modernize things it loses something in my opinion. I have read a few abridgments and modernizations only to find that they miss or add things the Author might not. It is hard work to do this but I sense this is a very good work.
