When Christians experience prolonged infancy and satisfaction with milk beyond normal infancy, they will have an immature and incomplete Christian worldview, which inevitably results in them advocating ideas that are merely human wisdom. George Barna’s research revealed, “Only 9% of all American adults have a biblical worldview…. [Those labeled] ‘born again Christians,’ the study discovered that they were twice as likely as the average adult to possess a biblical worldview. However, that meant that even among born again Christians, less than one out of every five (19%) had such an outlook on life.” I would add to this that what Barna requires to be considered as one who has a biblical worldview is not by any measure demanding, but is in my opinion quite minimal.
This dismal state of affairs is even more reason to return to an equipping model of the local church. If Christians do not have even a rudimentary understanding of Christianity, how can they communicate Christianity to a lost world, and how can they make biblical decisions in an ever-increasingly secular environment? If the shepherds themselves do not study deeply, they are utterly ill equipped to handle the task of engaging a hostile world.
They also are incapable of training those under their watch care beyond the most blatantly obvious truths of Scripture, which, when learned alone, are well suited for being reduced to clichés and the preferred diet of milkoholics (Christians who like to remain spiritually immature).
Man’s wisdom is not merely somewhat ineffective or unhelpful; it is as useless as a ship with no hull. Paul said, “The Lord knows the reasonings of the wise, that they are useless” (1 Corinthians 3:20). The consideration of what works in building the local church should always be evaluated by asking if it is human wisdom or divine wisdom as revealed in Scripture. If it is human, despite accolades received by the carnal, it is useless in building the temple of God regardless how fast or large the church grows.
 Barna Survey Examines Changes in Worldview Among Christians over the Past 13 Years, http://www.barna.org/barna-update/article/21-transformation/252-barna-survey-examines-changes-in-worldview-among-christians-over-the-past-13-years.
 A “biblical worldview” was defined as believing that absolute moral truth exists; the Bible is totally accurate in all of the principles it teaches; Satan is considered to be a real being or force, not merely symbolic; a person cannot earn his way into heaven by trying to be good or do good works; Jesus Christ lived a sinless life on earth; and God is the all-knowing, all-powerful creator of the world who still rules the universe today. In Barna’s research, anyone who held all of those beliefs was said to have a biblical worldview.
