2Ch 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.
2Ch 18:19 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.
2Ch 18:20 Then there came out a spirit, and stood before the LORD, and said, I will entice him. And the LORD said unto him, Wherewith?
2Ch 18:21 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.
2Ch 18:22 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.
Do you see that it was the LORD who commanded the evil spirit to entice Ahab to war by placing a lying spirit in the mouths of 400 prophets?
Ahab was wicked and God wanted Ahab destroyed.
God does not use sin just on the wicked.
You say God does not lead people into sin. All things were created by Him and for Him, for the glory of Christ, even satan and sin brings God glory. It was satan and sin that murdered our Lord Jesus Christ. If this ultimate sin had never happened were would we be? God foreordained the sacrifice of His Son before He ever created anything.
If God is sovereign, and He is, then God is in control of everything. For His purposes and for His glory. This includes the evil, God is in control.
