BibleStudyTools.com has added a classic volume to their digital library. One of the most influential, scholarly treatments of man as spirit, soul and body is A System of Biblical Psychology, by Franz Delitzsch. (Trans. Robert E. Wallis. 2nd, English ed. Edinburgh: T. & T. Clark, 1885.) The clarifications to the doctrine of sanctification in Delitzsch have enriched many, including Evan Hopkins who wrote The Law of Liberty in the Spiritual Life (which represented the essential message of the early Keswick Convention in England).
