For nearly 2,000 years, Christian mystics, martyrs, and sages have documented their search for the divine. Their writings have bestowed boundless wisdom upon subsequent generations. But they have also burdened many spiritual seekers. The sheer volume of available material creates a seemingly insurmountable obstacle. Enter the Upper Room Spiritual Classics series, a collection of authoritative texts on Christian spirituality curated for the everyday reader. Designed to introduce 15 spiritual giants and the range of their works, these volumes are a first-rate resource for beginner and expert alike. The Imitation of Christ by Thomas Kempis has perhaps influenced Christian spirituality more than any other book except the Bible. From the time of its appearance around 1420, it has been a best seller. This volume includes accessible selections from this classic of Christian spirituality and Western literature.
