As mainstream media cries out that the millennial generation has killed everything from cereal to office jobs, it must also be asked: have millennials killed Christian missions? With the rise of new technologies, social and political movements, and increasing numbers of religious nones, the church as we know it is facing serious turmoil at the hands of this new generation of adults. Here, a millennial and a baby boomer invite the reader into a dialogue about the future of missions and the future of the Western church. From a missiological reading of the Bible to the contemporary debate over Christian social justice and the ethical dilemmas of evangelism, this book plays out the intergenerational tensions within the church, and provides a platform from which to view the present and future of an institution that is so rapidly changing.
