John R. W. Stott (1921-2011) was known worldwide as a preacher, evangelist, and communicator of Scripture. For many years he served as rector of All Souls Church in London. A leader among evangelicals in Britain, the United States, and around the world, Stott was a principal framer of the landmark Lausanne Covenant (1974). His connections in and heart for the global church led him to found Langham Partnership. Langham continues its work today, equipping key leaders to preach God's Word clearly, faithfully, and relevantly in over 140 countries. Stott's many books, including Basic Christianity and The Cross of Christ, have sold millions of copies.
