I want to draw your attention to a book that is available on kindle for only £2.30.
It is called The Evidence of Prophecy, and is edited by Robert C. Newman. It looks at various prophecies in the Old Testament, showing how there is indisputable evidence of inspiration from God here. The book looks at prophecies relating to the nations, the nation of Israel, and the Messiah. It is an excellent book, and I have written a review on Amazon.
