But regarding the idea that God cannot lie, the Bible in 1 Kings 22:19-23 says the Lord (Jehovah) sent a lying/deceiving spirit! I recommend that people read it in various translations, including the KJV, NASB, and NWT. This passage when combined with the NT verses about God being incapable of lying, is one of the many examples of a possible contradiction in the Bible, and is thus part of the very strong evidence against the Bible being God's (any always truthful all-knowing god's) word. In the KJV the passage says the following.
' 19 And he said, Hear thou therefore the word of the Lord: I saw the Lord sitting on his throne, and all the host of heaven standing by him on his right hand and on his left.
20 And the Lord said, Who shall persuade Ahab, that he may go up and fall at Ramothgilead? And one said on this manner, and another said on that manner.
21 And there came forth a spirit, and stood before the Lord, and said, I will persuade him.
22 And the Lord said unto him, Wherewith? And he said, I will go forth, and I will be a lying spirit in the mouth of all his prophets. And he said, Thou shalt persuade him, and prevail also: go forth, and do so.
23 Now therefore, behold, the Lord hath put a lying spirit in the mouth of all these thy prophets, and the Lord hath spoken evil concerning thee.'
The ASV Bible in verse 20 instead of saying "persuade" says "entice" and the footnote says "Or, deceive".
Hypothetically speaking, if the WT and its Governing Body are receiving communications from demon lying spirits and if Jehovah exists, then based upon 1 Kings 22:19-23 those demon lying spirits might have sent by Jehovah to deliver those messages. Furthermore, the Revelation says God will use demonic spirits to lead the 10 kings of the Earth into the Battle of Armageddon.
