Before he died, Pope John was asked what church doctrine most needed emphasis today. He replied, "The doctrine of the Holy Spirit.” Billy Graham asked Dr. Karl Barth what he thought the next emphasis on theology would be. He replied without hesitation, “The Holy Spirit.”
Doctor Graham expressed concern over the misunderstanding and even ignorance in some Christian circles concerning the Third Person of the Trinity. How the Father, Son and the Holy Spirit relate is explained as follows: …we say that we pray to the Father through the Son and in the power of the Holy Spirit. …functionally the Father came first, then the Son became incarnate, died and rose again. Now the Spirit does His work in this age of the Spirit….trinitarianism preserves the unity of the Godhead, and at the same time it acknowledges that there are three persons in that Godhead which is still of one essence. God is one, but that oneness is not simple - it is complex. God the Father is fully God. God the Son is fully God. God the Holy Spirit is fully God. The Bible presents this as fact….although the Father is the Source of all blessing, it is through the Holy Spirit at work in us that all truth becomes living and operative in our lives.
I have presented evidence from neuroscience in my books and in several blogs posted to date that confirm dualist interaction between the immaterial Spirit of God and the human spirit and soul through the material neural synaptic networks of the human brain. The human cognitive capacity to interpret linguistic neural codes actualized within spike trains of action potentials enables work of the Holy Spirit within us.
