NLT 1 Kings 22:19-23, “I saw the LORD sitting on his throne with all the armies of heaven around him, on his right and on his left. And the LORD said, ‘Who can entice Ahab to go into battle against Ramoth-gilead so that he can be killed there?’ There were many suggestions, until finally a spirit approached the LORD and said, ‘I can do it!’ ” ‘How will you do this?’ the LORD asked. “And the spirit replied, ‘I will go out and inspire all Ahab’s prophets to speak lies.'” ‘You will succeed,’ said the LORD. ‘Go ahead and do it.’ “So you see, the LORD has put a lying spirit in the mouths of your prophets. For the LORD has determined disaster for you.”
This passage shows that God held a meeting with some demons, (among the other host of Heaven). God proceeded to enticed them, and then He picked one particular convincing lying spirit. He gave it His divine pronouncement of success.
It was mentioned before that God wanted to kill Ahab, and so He decreed a situation to facilitate this. And so, God did not allow this; rather, it was God who first voiced up the idea of wanting Ahab to sin, by going to war when God told Ahab not to: “’Who can entice Ahab to go into battle so that he can be killed.” With demons who love to harm people and lie, God “enticed” them by telling them of His plan of destroying Ahab. Demons love to destroy people! If there was ever a situation where the definition of enticed belonged, it is here. It was not a demon who first said, “let us help Ahab sin by going to war so that God will have even more reason to kill him”; rather, this was God’s initiative. God merely picked out, one particular zealous demon, after enticing it with His original idea. “All that God does is just.” –by definition.
“But if the [false] prophet is prevailed upon to speak a word, it is I, the LORD, who have prevailed upon that prophet, and I will stretch out My hand against him and destroy him from among My people Israel.” (NASB).
There is no demon or lying spirit mentioned here. Scripture says God directly “enticed or persuaded” a human mind to give a false prophecy, and then judged them for breaking His commandment.
So what if God uses a demon? These so-called secondary causes (like lying spirits) are created by God, first enticed by God, are sustained in reality by God, directed by God and even have their own hearts and feet secretly directed by God. All things in creation move live and have their being in God (Acts 17). This means that the popular phrase “secondary causes” is an defective phrase. The objects in question are not “secondary” in relation to God, and His direct and absolute control of them, even their minds and thoughts.
Think of a game like checkers, or chess. The ultimate level is saying, “Oshea moves white pawn.” But on the relative level, “white pawn moves to E4.” Or in propositional logic, going from ultimate ontology to relative.
(P) If Oshea directly moves black bishop to B3, (Q) then the necessary result is that black bishop will take white pawn on B3.
This is saying, “God directly causes all things; thus, God directly causes specific x, y or z.” If God ultimately causes all things, then God ultimately is the author for all rain. Or. If God ultimately causes all things, then God ultimately is the author for all sin.
We already know that God is not what he creates. This is an obvious and elementary doctrine. If God causes the Nile to flow north, God is Himself, not a north flowing river.
In relation to God who directly controls all things, there is no such thing as “secondary.” Therefore, the term secondary cause is a false category if applied to in relation to God’s activity. And so, it is not in man or demons to direct their steps, God does; with or without them knowing it. In the since of metaphysical(causality) and orchestrating God is the author of evil.
When the Scripture goes behind the scene and show what is happening, it always shows God in this level of absolute sovereign control. Now, most of the time the Scripture speaks on the relative level; for example Jesus saying “your faith has healed you.” Yet, when the Scripture do go to the ultimate level it is always said God is the ultimate cause of all things with no secondary causes involved. This is the Sovereign God of Scripture, anything less is paganism.
Because God is the author of evil in the sense of initiating, and orchestrating and being in control of the metaphysical, it was not said that the LORD allowed a lying Spirit to be in the mouth, but that “the LORD has put a lying spirit in the mouth.”
