The Christian Introvert

The modern Christian church, perhaps especially the evangelical church, is designed almost exclusively for extroverted individuals. What's wrong with this model? It excludes or even alienates and fails to minister effectively to perhaps as much as 50% of the population. Using Myers-Briggs evaluations, 50.9% of those surveyed fall into one of the 8 introverted personality types. Other recent surveys have also backed up this data, so it is fairly safe to say fully 1/2 the population is or leans toward introversion. This also means that is likely 50% of the people sitting in the pew each week at church are introverted and therefore likely uncomfortable in that environment. So why does the modern church continue to focus on that model?
