One can also do word analyses and various grammatical and syntactical searches of the New Testament or related writings with a speed, ease, and comprehensiveness previously undreamt of. Ease of access to reference works eliminates tedious book hunting and page turning. A downside is that every decade we move farther into computer technology, the greater the danger becomes that younger scholars will lack the hands-on intimacy with the text that pen and paper demanded, and the ingrained, deeply intuitive grasp of the text that a trained memory can arrive at. Voluminous information easily accessible can not only obscure but actually stunt creative and historically responsible scholarship.
