The diligent expositor can argue that, in time, he will deal with every truth that Scripture teaches and that the gospel message will be included throughout. However, there is a sense in which gospel preaching can be defined in a more particular sense as 'the presentation of the Christian message to sinners calling them to repentance towards God, faith in our Lord Jesus Christ, conversion and subsequent holiness of life'. Gospel preaching is evangelistic preaching that demands urgent response. There has been a revival of doctrinal and serious ministry. This is wonderful, but this blessing can 'breed worms'.
Churches become intellectually top-heavy.
The minister is so involved in working through profound passages of Scripture that an unsaved person is utterly bewildered. It is not always that he rejects the message, but that the message is often too intellectual. The gospel may be implicit in evangelical preaching without the challenge being explicit enough to produce a response. Of course, the Holy Spirit is sovereign, but this does not excuse us from preaching the gospel clearly, directly and with passion. There is understandable fear that preaching can be trivialised.
