Evangelism shouldn't be an impromptu event, cropping up only infrequently - and awkwardly even then - and timidly supportive of any inclination to religion or spirituality that the other person holds. As Christians, this should be an appalling representation of our Great Commission. Christians should be bold about the Gospel with other Christians as well as sinners, praying and planning and working together to bring the Gospel more into our lives as well as the lives of those around us. In The Gospel & Personal Evangelism Mark Dever has written a book, both instructive and encouraging, for all Christians in the same spirit that he motivates us to move towards.
In about a hundred pages, Dever discusses modern apprehensions towards evangelism, what the Gospel and evangelism are (and are not), who, how and why we should evangelize, and what we should do after presenting the Gospel. He minces no words, stripping his message down to the basics, and covers the topics thoroughly while leaving nuances and theory to other writers. Depth isn't his intention here, as the subject is already incredibly deep. This is for those of us who have the knowledge of the mandate to evangelize, recognize the persuasion of the Holy Spirit to do so, and have enough compassion for a fallen world to impel us to follow His leading.
