Deut. 18: 21-22, "21 And you may say in your heart, 'How shall we know the word which the Lord God has not spoken?' 22 When a prophet speaks in the name of the Lord, if the thing does not come about or come true, that is the thing which the Lord has not spoken ...."
Num. 23: 19, "19 God in not a man, that He should lie, nor a son of man, that He should repent: has He said, and will He not do it? Or has He spoken, and will not make it good?"
I Sam. 15: 29, "29 And also the Glory of Israel will not lie or change His mind; for He is not a man that He should change His mind."
Many have heard these passages read in their churches, and have read it for themselves in the bible. This is the measure to use in measuring any statement, because it is apparent that God would not inspire a vain pronouncement. Unfortunately, there are such vain pronouncements and prophecies in the bible. We will look at a false pronouncement of the Book of Jeremiah. The pattern I will follow is to quote the verses in question, and provide an observation based on easily attainable historical information, and provide a conclusion based on the truth. I have no reason to lie about what follows, the bible itself proves its own unreliability. I have even incorporated the most common apologetic, and pointed out its' mistakes; judge for yourself.
Jeremiah 46: 13-26, "13 This is the message which the Lord spoke to Jeremiah the prophet about the coming of Nebuchadnezzar king of Babylon to smite the land of Egypt ... 19 for Memphis will become a desolation; it will even be burned down and bereft of inhabitants ... 24 the daughter of Egypt has been put to shame. Given over to people of the north ... 26 and I shall give them over to the power of those seeking their lives, even into the hand of Nebuchadnezzar king of Babylon and the hand of his officers ...."
Apologetic: Still to be fulfilled.
Rebuttal: Nebuchadnezzar is dead, and so is his empire; the prophecy cannot be fulfilled.
Observation: v, 19 states that Nebuchadnezzar would desolate Memphis, that never happened. God never gave over Egypt to Nebuchadnezzar, who in 601/600 battled the Egyptian army and suffered such heavy losses that he returned to Babylon to recover. Nebuchadnezzar never could enter Egypt. Even for those who refuse to look outside the bible for information on the ancient world, cannot change the FACT, that even the bible does not admit that the prophecy came true.
Conclusion: According to the measure of Moses, this is a false prophecy.
Special Note: Jeremiah did everything in his power to stop the kingdom of Judah from making an alliance with Egypt, he undermined the city and the populations moral, and encouraged it to surrender. When it was destroyed, by Nebuchadnezzar, Jeremiah ended up in the service of the Babylonian king. There is even sufficient evidence in the bible to argue that Jeremiah was a fifth-columnist, and was so fanatical about destroying the royal house of Judah, that he sold out to the only king with sufficient power to do the task.
So who are you going to believe? Your preacher? Your bible? Moses? The facts? That I leave to you, it is sufficient that the bible was proved to be in error, that prophecies attributed to God, were false words put into His mouth.
