What is inspiration, anyway?

"What is the inspiration [of the Bible] can never be properly defined—there is a mystery therein. It is a mystery of the divine-human encounter. We cannot fully understand in what manner 'God's holy men' heard the Word of their Lord and how they could articulate it in the words of their own dialect. Yet, even in their human transmission, it was the voice of God. Therein lies the miracle and mystery of the Bible, that it is the Word of God in human idiom."—Pentecostalism as a Christian Mystical Tradition, pages 114–15, quoting Ervin, "Hermeneutics: A Pentecostal Option," Pneuma 3.2 (1981): 17–18, quoting Georges Florovsky, Bible, Church, Tradition: An Eastern Orthodox View (Belmont, MA: Nordland Publishing, 1972), 27
