From the preface of Torrance's Incarnation

For Torrance, theology is personal knowledge of God in which mind and heart together are equally involved. God is personal, or ‘personalising person’ as Torrance used to say, the one who makes us personal and can only be known personally. One cannot therefore study theology without personal knowledge of God in faith. It can never be simply an academic exercise. Theology involves faith and worship and can only properly be done on one’s knees.—Incarnation: The Person and Life of Christ, xxix–xxx
