But the problem is this...
How could use any man as His "pen," if that person is totally corrupt?
How could He give the Prophet the words to write?
Do you blow your nose with used toilet paper?
God is not going to have the writers of Scripture be corrupt while receiving His words to write.
God moved them to write precisely what He wanted written. It didn't originate with the men who did the writing.
[2Pe 1:21 KJV] 21 For the prophecy came not in old time by the will of man: but holy men of God spake [as they were] moved by the Holy Ghost.
