"Without the prophet the church becomes a spirit-less organization in which even apostolic work hardens into a new form of religious bureaucracy and without the prophetic thrust the teaching ministry perpetuates cycles of timeless truth but is deaf to what the Spirit is now saying to the churches. Without a prophetic voice challenging God's people to lay down their lives for the world, pastoral nuture can easily degenerate. Evangelism too, desperately needs to hear the prophet if it's methods are to be as godly as it's message and if it is to avoid giving stereotyped answers to questions people are not asking".
