Although sometimes popularly associated with instantaneous change, the experience may take place over a longer period of time and, in any case, is usually preceded by preparatory influences and explorations. Conversion is not self-defeating. Its exact nature and form depend upon the expectations of the belief system to which one is converted and, furthermore, upon the personality characteristics of the convert. Conversion can be described as intellectual, moral, or religious, depending on its focus in the human experience. In Christian conversion all three dimensions come into view, although differing accents appear in the various Christian traditions.
Conversion translates the biblical terms for turn or return.
In the Old Testament the concept refers to the return of the people of God after leaving the way of God. The return involves both a spiritual renewal of relationship to God in covenant and a moral change toward upright living. It implies a restored life in community with the people of God. The New Testament takes up this viewpoint while expanding it. Conversion is given a special meaning by its linkage to Jesus' kingdom teaching.
