During the 1720s, John Wesley began his quest to understand biblical holiness theologically and to experience it personally. Over the following decades, he preached and wrote about sanctification, carefully refining his grasp of the subject. This long-term investigation led him to study Scripture, reason, experience, and the Christian tradition. Then, in 1766, he published A Plain Account of Christian Perfection. That book went through several revisions and expansions, and in 1777, he issued his final edition of this work. Wesley’s Plain Account of Christian Perfection became a Christian classic that now stands in the company of such devotional works as Thomas à Kempis’s Imitation of Christ, William Law’s Serious Call to a Devout Holy Life, Richard Baxter’s The Reformed Pastor, and Jeremy Taylor’s Holy Living and Holy Dying. This edition of the Plain Account is a transcription provided by one of the leading Wesley scholars in the world.
