To those who believe God knows the future:

Jon 3:4 And Jonah began to enter the city on the first day’s walk. Then he cried out and said, “Yet forty days, and Nineveh shall be overthrown!”

2Ki 20:5 “Return and tell Hezekiah the leader of My people, ‘Thus says the LORD, the God of David your father: “I have heard your prayer, I have seen your tears; surely I will heal you. On the third day you shall go up to the house of the LORD.
2Ki 20:6 And I will add to your days fifteen years. I will deliver you and this city from the hand of the king of Assyria; and I will defend this city for My own sake, and for the sake of My servant David.” ‘ ”

How can a God who cannot lie make specific time-limit prophecies that do not come true when He said they would?
