This thesis investigates the expository preaching of John Stott(U.K.) and Han Hum Oak(Korea) on Romans, examining their individual methods of exegesis, interpretation, application and communication. The purpose of this thesis is to investigate what constitutes true expository preaching by means of a critical comparison between a Western and an Eastern preacher, attempting to highlight the different strengths and weaknesses arising out of each cultural and personal proclivity. To fulfil this purpose, the thesis consists of four chapters. Chapter 1 examines and analyses critically expository preaching by looking at contemporary preaching and its use of the processes of exegesis, interpretation, application and communication. Chapter 2 deals with various aspects of John Stott’s perspective on text-centered expository preaching. By analyzing actual sermons on Romans by Stott, his practice as he moves from text to preaching is examined. Chapter 3 analyses Han Hum Oak’s perspective on transformation-centered expository preaching, following the same structural analysis and critical evaluation as that used for Stott. The final chapter attempts a critical comparison of John Stott and Han Hum Oak, evaluating the contributions of each in the context of the society in which they preach as modern expository preachers. It concludes with some lessons about expository preaching that can be drawn from this comparative evaluation..
