“The nature of conversion has been much discussed. As I have already noted, a convert is a person who, having formerly held one set of beliefs or values is persuaded to adopt other beliefs or values; these may be radically different from those he held formerly.
Conversion, and especially religious conversion, never occurs, as it were, in a vacuum. Protestant evangelism tends to lay stress on what has been called "crisis conversion". In other words, conversion is a crisis event in the life of the Person concerned. It can be, and often is, a very real and meaningful experience. "Crisis conversions" often occur within the context of "crusades" or other large evangelistic meetings. An "evangelist" who is skilled in this type of work delivers an impassioned address. Usually he is supported by a talented soloist who sings heart-rending "gospel songs". There will be a well-rehearsed choir. The whole purpose of the proceedings is to play upon the emotions of those present. The evangelist's address ends with an "appeal" to those who wish to make a decision for Christ to come to the front. They are then led off to be "counseled."
