“Too few Christians today have an adequate grasp of biblical doctrine. This is due to a widespread disinterest in doctrinal preaching and deep reading. . . . This problem, though intensified in our day, is not new. Eighty years ago J. Gresham Machen lamented: ‘The growth of ignorance in the Church is the logical and inevitable result of false notion that Christianity is a life and not also a doctrine; if Christianity is not a doctrine then of course teaching is not necessary to Christianity'” (Kenneth L. Gentry, He Shall Have Dominion, 40).
