The Scriptures declare it, as I have shown. The Scriptures assert it.
I already did show you.
Jesus quoted the Old Testament Scriptures.
No, they are direct statements. (1 Thess. 2:13) "...when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe." (2 Peter 3:15-16) "....even as our beloved brother Paul also according to the wisdom given unto him hath written unto you; As also in all his epistles....which they that are unlearned and unstable wrest, as they do also the other scriptures, unto their own destruction."
"Thus saith the LORD" indicates the origin of Scripture. Thus when it is written down, through the work of the Holy Spirit of God, it is God Authored. (Ex. 17:14) "And the LORD said unto Moses, Write this for a memorial in a book, and rehearse it in the ears of Joshua:..." (Ex. 34:27) "And the LORD said unto Moses, Write thou these words: for after the tenor of these words I have made a covenant with thee and with Israel."
The Bible is the Word of God.
