The go-to-verses for considering “inspiration” of scripture are 2 Timothy 3.16,17:
“All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, that the man of God may be competent, equipped for every good work.”
Early today I read a great description of the process of inspiration. Like any attempt to explain the things of God there is a limitation because we only have words and our “through a glass darkly” understanding.
But I really enjoyed this; perhaps you will also. It is from the book Unbreakable – What the Son of God Said About the Word of God by Andrew Wilson:
“Consider a jazz musician who can play all sorts of different instruments. Nobody, listening to Louis Armstrong, would ask whether the music was being made by Louis or by his trumpet; everybody knows that the breath and the tune come from Louis, but the instrument through which the breath passes, in order to become audible, is the trumpet. The Bible writers, if you like, are the instruments of revelation – a trumpet here, an oboe there, a saxophone here – and they all make different sounds. But the musician, the skilled artist who fills them all with his breath and ensures the tune is played correctly, is the Holy Spirit. That’s kind of how inspiration works.”
