The bible was originally called " Hebrew Scriptures, and were never " divinely inspired'. It was simply their story about the journey of the Hebrews, their belief system and their rituals.
It was Christians who took the book, changed its name to " Old Testament".
If I believe I can walk on water on faith, can I ?
You have already illustrated a heroic lack of faith, so how do you propose you could?
That was because Christ, who intervened in nature,
creating food, walking on water(without pontoons mind you), becoming undead, calming storms with his word, said that what we now call the "Old Testament" was indeed Gods word, and that Gods word stands forever and cannot be broken...
the Jews of his time argued with him cause they felt their
word (Old Testament) was Gods word, and argued from it
to try and disprove Jesus (known as the Christ, or anointed one)
Where in the world did you get the idea that the Jews
(other than the unbelieving Jews) thought that the
"Old Testament" was not Gods word?
