In order to be effective in evangelism, one must clearly understand the dynamics of conversion. Richard Peace here examines two very different conversion experiences in the New Testament — Paul's and the twelve disciples' — and explores their implications for contemporary evangelism.

The unique feature of this book is Peace's carefully argued proposal that Mark structures his Gospel around the unfolding conversion of the Twelve. By showing how conversion can take place either suddenly or gradually over time, Peace gives good reasons, and suggests practical ways, to replace one-sided evangelism techniques with more holistic methods.
