Gaps in vocational ministry — expository preaching, apologetics, archaeology, worship leading

Mike identifies three key gaps: (1) Skilled worship leaders — churches are severely lacking. (2) Expository, exegetical, verse-by-verse preaching — many pastors do not know how to study and teach the Bible well. (3) Apologetics — especially archaeology apologetics, which lacks a popularizer the way William Lane Craig has popularized philosophical arguments. He suggests sensing a need in the church may be a calling signal.
