Theology vs methodology

"The essential secret [to preaching] is not mastering certain techniques, but being mastered by certain convictions. In other words, theology is more important than methodology. ... To be sure, there are principles of preaching to be learned, and a practice to be developed, but it is easy to put too much confidence in these. Technique can only make us orators; if we want to be preachers, theology is what we need." (John Stott, Between Two Worlds, Eerdmans, 1982, pp 92)
