The experience of salvation regarded from the psychological point of view is crucial for the understanding of the psychology of Evangelicalism. The whole drama of Incarnation, Atonement and Resurrection finds its meaning in relation to that experience. The need of Salvation is a theological dogma; but it is also an experience common to the devotees of every religion. Unfortunately, both religious and psychological volumes have laid an exaggerated emphasis on those whose sense of need approximated to a psycho-neurosis. Religious values and the religious sentiment take a central place in motivation and in the ordering of their lives. The spiritual unity of their lives is rooted in the rational and moral need; and generally this kind of unity gives a more comprehensive harmony to behaviour tendencies. The power of evangelical religion to make the vilest clean is too well attested for anything we have written to rob triumphs of their glory.
