All scripture is inspired by God and is useful for teaching

"All scripture is inspired by God and is useful for teaching, for refutation, for correction, and for training in righteousness, so that one who belongs to God may be competent, equipped for every good work."  (2 Timothy 3: 16 - 17)

On Inspiration, Knapp writes:  "An extraordinary divine agency upon teachers while giving instruction, whether oral or written, by which they were taught how and what they should speak or write."

This is my experience.

The Holy Spirit is the source of all inspiration and power.
