From the vantage point of living on another continent and being able to look at US Christianity more objectively, Ryan Porter identifies the gospel deficiency in current Western Christianity - we are Gospelsick. Using his lens of medicine, he both diagnoses the church's illness and provides the treatments needed to recover from the deficiency.

Gospel Deficiency (n.): the inhibition or minimization of the gospel of Jesus Christ in the lives of his followers (those in the church), characterized by increased fear and obsession with worldly interests, and leading to a decrease in the benefits of the world-changing gospel in us and in our proclamation of it to others.
