1 Kings 22:23
So now the LORD has put a deceiving spirit in the mouths of all these prophets of yours. The LORD has decreed disaster for you.
Typical Arminian misunderstandings.
Isaiah 45:7
I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.
Deuteronomy 32:39
See now that I, even I, am he, and there is no god with me: I kill, and I make alive; I wound, and I heal: neither is there any that can deliver out of my hand.
Isaiah 53:10
Yet it was the LORD’s will to crush him and cause him to suffer, and though the LORD makes his life an offering for sin, he will see his offspring and prolong his days, and the will of the LORD will prosper in his hand.
Who caused Jesus to suffer? The men who crucified him? God says He caused Jesus to suffer. How can you understand this mystery, unless you understand God caused the men to sin in causing Jesus to suffer?
Genesis 50:20
But as for you, ye thought evil against me; but God meant it unto good, to bring to pass, as it is this day, to save much people alive.
My position is not that God plays the part of Satan, nor that He pretends anything. So your question is irrelevant to me. My position is that God causes Satan to play Satan's part. That is, He causes Satan to exist in order to work out everything for His purpose. By the way, do you know what God's ultimate purpose is?
You are quite deceptive in your writings. My position is not that God commands demons just because He can. Though you make it look like that's my position. My position is that He causes sin specifically in order to accomplish His great purpose.
1 Kings 22:22
’I will go out and be a deceiving spirit in the mouths of all his prophets,’ he said. “’You will succeed in enticing him,’ said the LORD. ‘Go and do it.’
Spirit: "I will go out and deceive."
God: "Go and deceive."
Renniks: "God, you don't do that! You don't command such things! That is a silly idea! It's absurd! I refuse to believe it!"
1 Kings 22:23
So now the LORD has put a deceiving spirit in the mouths of all these prophets of yours. The LORD has decreed disaster for you.
Renniks: "God, you didn't do that! You don't decree disaster! You didn't put the deceiving spirit in those prophets, you merely allowed the deceiving spirits to go in them. You can't, because you don't cause people to sin! I refuse to believe it!"
So that one verse which you misinterpret is all you have?
Let's look at the whole story instead of laser focus on one verse and applying it universally.
2 Chron. 18:18 Again he said, Therefore hear the word of the Lord; I saw the Lord sitting upon his throne, and all the host of heaven standing on his right hand and on his left.19 And the Lord said,
Who shall entice Ahab king of Israel, that he may go up and fall at Ramothgilead? And one spake saying after this manner, and another saying after that manner.20 Then there came out a spirit, and stood before the Lord, and said, I will entice him. And the Lord said unto him, Wherewith?21 And he said,
I will go out, and be a lying spirit in the mouth of all his prophets. And the Lord said, Thou shalt entice him, and thou shalt also prevail: go out, and do even so.22 Now therefore, behold, the Lord hath put a lying spirit in the mouth of these thy prophets, and the Lord hath spoken evil against thee.
Same story, but in Kings:
1 King. 22:19 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.
God did not select a spirit and tell him
“This is what I will cause you to do through predestination.
He allowed the spirit to do what he already planned to do anyway.
In your system, God would select the spirit and cause him to act. That's not what happened.
God doesn't cause sin..he certainly didn't cause Ahab to sin.
God simply allowed King Ahab to do what he already wanted...to listen to his false prophets.
Ahab was not thankful for God’s warning to him, instead he was resentful once Micaiah gave him the word of the Lord. God extended even more patience toward Ahab by having Micaiah tell the king exactly what evil spirits had been doing to plot his downfall, but Ahab rejected this further warning as well. If God’s intent was to command demons to lie and deceive Ahab, why would He bother warning Ahab about it?
Determinists quote only certain phrases in 1 Kings 22 so it sounds as though God is the direct causal agent to what happened, but if we are honest and read the whole context we get another picture.
