Faith as ultimate concern is an act of the total personality. It happens in the center of the personal life and includes all its elements. Faith is the most centered act of the human mind. It is not a movement of a special section or a special function of man's total being. They all are united in the act of faith.

Out of the element of participation follows the certainty of faith; out of the element of separation follows the doubt in faith. And each is essential for the nature of faith.

Otherwise it would be indifference.
