Talbot Davis makes a helpful point about the process of divine inspiration with respect to the letters of Paul:
Muslims contend that the Koran is straight dictation — all Allah, with no Mohammed filter at all.
The Christian conception of the bible is quite different. We
believe the God-breathed message of the Word gets delivered most
compellingly through the passions and personalities of the various
authors.Because if God can take a curmudgeon like Paul and turn him
into a composer of inspired texts, imagine what he can do with you and
me.
Davis explains Paul’s use of a scribe, to whom he dictated his letters. Along the way, Davis shows us that this in no way undermines the doctrine of inspiration, but rather upholds it and makes it uniquely Christian.
