Bible says God cannot lie.
Hebrews 6:18
in which it is impossible for God to lie
Numbers 23:19
God is not a man, that he should lie; neither the son of man, that he should repent.
Titus 1:2
In hope of eternal life, which God, that cannot lie, promised before the world began.
Bible says God does lie and will even make prophets or 'lying spirits' do his dirty work.
1 Kings 22:23
Now, therefore, behold, the Lord hath put a lying spirit in the mouth of these thy prophets, and the Lord hath spoken evil concerning thee.
Ezekiel 14:9
And if a prophet be deceived when he hath spoken a thing, I the Lord have deceived that prophet.
Jeremiah 4:10
Ah, Lord GOD! surely thou hast greatly deceived this people.
Jeremiah 20:7
O Lord, thou hast deceived me, and I was deceived.
Thessalonians 2:11
For this cause God shall send them strong delusion, that they should believe a lie.
Believers need believe in regard to the former, that the Bible is always in context and in regard to the latter, that the Bible is always out of context.
This way believers can also join in with the lying themselves.
1 Kings 22:23
Now, therefore, behold, the Lord hath put a lying spirit in the mouth of these thy prophets, and the Lord hath spoken evil concerning thee.
I already showed that God did NOT lie or coerce anyone to lie or coerce anyone to believe the lie in what took place. The passage says that God asked for a volunteer and a lying spirit volunteered to accomplish God’s judgment. God is always right to judge sin.
Ezekiel 14:9
And if a prophet be deceived when he hath spoken a thing, I the Lord have deceived that prophet.
I already showed that this verse does not state that God Himself has lied, but rather that God was not going to reveal His truth to the false prophet, the one that had rejected His truth already, or to the listeners to a false prophet. Although in this passage it does not directly state how God was going to accomplish this, the set up is exactly the same as it was in 1 Kings 22, prophets who were already deceivers, and people who had already rejected the truth. What is missing is whether or not God had sent a lying spirit to accomplish the judgment. It’s simply not stated, yet I would think that it is likely the case that it played out in a similar manner as in 1 Kings 22, especially when considering that there are multiple other verses that show that Satan and fallen angels actively deceive people, even today.
Jeremiah 20:7
O Lord, thou hast deceived me, and I was deceived.
Different translation:
LORD, you have persuaded me, and I was persuaded. You are stronger than I am, and have prevailed. I have become a laughing-stock all day long; everyone mocks me. NHEB
The second translation gives a clearer meaning.
If you read the verse in context to its passage you will see that Jeremiah is complaining about becoming a prophet because he has been persecuted by the people for preaching a message of coming judgment that they don’t want to hear. They prefer the false prophets who foretell peace.
The passage begins with this:
Jeremiah 20:1, 2
When the priest Pashhur son of Immer, the official in charge of the temple of the Lord, heard Jeremiah prophesying these things, he had Jeremiah the prophet beaten and put in the stocks at the Upper Gate of Benjamin at the Lord’s temple.
Jeremiah was honest with God about his feelings that being a prophet wasn’t what he expected it to be. Even though he is feeling this way and speaking freely to God, it does not mean that God actually lied to him.
Jeremiah 4:10
Then said I, Ah, Lord GOD! surely thou hast greatly deceived this people and Jerusalem, saying, Ye shall have peace; whereas the sword reacheth unto the soul.
According to several commentaries, it could be the false prophets making this claim. This doesn’t really make sense to me, because the false teachers were the ones proclaiming peace, so why would they be upset with God for this?
It is also possible that Jeremiah did speak this. However, Jeremiah’s message recorded so far in the book of Jeremiah was not one of peace, but of coming destruction. So, this would seem to make his accusation false.
I’m undecided as to what the verse actually is referring to, but it does make a little bit of sense to me that it could be Jeremiah is speaking to God concerning the false prophets and their message of peace and that the people have been deceived by the false prophets. Perhaps he is remembering the previously written passage in 1 Kings 22 where God sent the lying spirit to the false prophets, and Jeremiah is seeing that God has given the people over to be deceived by the false prophets.
However, in both scenarios, God did not lie.
Lies are from the devil, not God:
John 8:44-46
You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it. 45 But because I tell the truth, you do not believe Me. NKJV
Demons are the evil spirits who follow after Satan (the devil). When God allows a spirit to deceive someone, it will be the work of an evil spirit. God is allowing sin to be shown as evil with ongoing consequences. This takes place at multiple levels, from what we see taking place on earth and also what is transpiring in heaven with the spirits. Ultimately, even the lying spirit (a demon) will give an account to God for his sin. Demons know this and shudder (James 2:19), though they keep on sinning. Jesus said that the problem with those challenging Him was that they were of their father the devil, and they wanted to do the desires of their father, not God. When Jesus told them the truth, they did not believe Him.
God makes it clear that He has the right to rule and judge. When God says that if a person rejects the truth, that God then reserves the right to give the person over to believing the lies the person wants to be true, then He has the right to do this. Our responsibility is to find what God wants and submit to it. Anything else is a losing battle on our end. When we hear about this, God wants us to respond in fear that we might cross a line, such that He stops trying to impress truth upon us.
When we reject truth because we don’t like it and then blame God for the problems resulting from this, it actually only serves to demonstrate God’s wisdom in how he handles the situation. He gives us the will to accept or reject. However, continued wilful rejection of truth and coming up with our own standards of right and wrong offends Him and a consequence may be that we believe the lies that we want to be true.
Hebrews 2:2, 3a
For if the word spoken through angels proved unalterable, and every transgression and disobedience received a just penalty, how will we escape if we neglect so great a salvation? NASB
God has offered salvation through Jesus to all who believe. There are strong warnings to not harden one’s heart and reject Him.
One of my favorite passages in the Bible foretells of Jesus as One Who was not violent or deceiving.
Isaiah 53:8d, 9
...for the transgression of my people he was punished.
He was assigned a grave with the wicked,
and with the rich in his death,
though he had done no violence,
nor was any deceit in his mouth.
