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. But faith is not the sum total of their impacts. It transcends every special impact as well as the totality of them and it has itself a decisive impact on each of them.
