In Showing the Spirit, Carson speaks to one of evangelism’s most troublesome issues: spiritual gifts. The book expounds the crucial passage, 1 Corinthians 12–14. Partisans on both sides of charismatic issues are challenged by the unbiased consideration of nuances in the Greek text found in 1 Corinthians. Carson interacts with some other Christian doctrines, as well as with findings of linguists, social anthropologists, and historians. The concluding chapter integrates material from other portions of Scripture—especially the Book of Acts—so that the author’s conclusions reflect all of the biblical evidence. 'We must even-handedly attempt to weigh all the relevant evidence,' Carson writes, 'even while we insist that the authority of Scripture must prevail.'
