In the last episode of the podcast (LBM Podcast 0004) we covered a false prophecy of the Watch Tower Bible and Tract Society. I am going to outline this false prophecy in this post and provide the documentation so you can use this in your discussions with JWs.
In Deuteronomy 18:20-22 God gives us the requirements for a prophet that is from Him. If the prophet makes a prediction about anything that does not come to pass he is a false prophet and should not be trusted.
Deuteronomy 18:20 But the prophet who presumes to speak a word in my name that I have not commanded him to speak, or who speaks in the name of other gods, that same prophet shall die.’ 21 And if you say in your heart, ‘How may we know the word that the Lord has not spoken?’ 22 when a prophet speaks in the name of the Lord if the word does not come to pass or come true, that is a word that the Lord has not spoken; the prophet has spoken it presumptuously. You need not be afraid of him. ESV
