Sanctification: Seeing Life Through a Sacred Lens suggests that sacred matters represent a vital interest for the psychology of religion. The articles throughout this special issue propose that individuals can perceive virtually any aspect of their lives as having divine character and significance. Several implications of sanctification for human functioning are discussed: people invest a great deal of time and energy in sacred matters; people go to great lengths to preserve and protect what they perceive to be sacred; sacred aspects of life elicit spiritual emotions; sanctification offers a powerful personal and social resource individuals can tap throughout their lives; and the loss of the sacred can have devastating effects. The articles illustrate initial findings in this area of theory and research, and generate questions to stimulate further explorations into this relatively uncharted area of study.
