This passage asked the question "does God know the future? Then it answers it with an absolute affirmative. Yes God does know the future because He ordained the future, the determined every thing that is to happen. This, according to the Bible, sets Him apart from the false God's that the nation of Israel was worshipping . According to Isaiah 46:10 , God declares the end at the beginning . This is what Bible prophecy is all about-God declaring something years before it ever comes to pass. God knew from before the world was created who is going to be saved because He decided who is going to be with Him in Glory.
