in considering the source and inspiration for the bible one must see what the bible says of itself. several verses of scripture define the source, intent, and author. 2 peter 1:21 says this - "no prophecy was ever made by the act of human will, but men moved by the holy spirit spoke from god." isaiah 55:11 tells us that his is a word of power - "so shall my sword be that goes forth from my mouth; it shall not return to me void, but it shall accomplish what i please, and it shall prosper in the thing for which i sent it." hebrews 4:12 says this - "for the word of god is alive and active. sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart."
