"The text says this!"
"Yeah but... it means the exact opposite."
Because certain Christian theology needs it to say something else.
God allowed the Persian king to take Israel into captivity as part of His judgement against Israel for following false gods, but He didn't cause it. Does God "Create" Evil?
In Isaiah 45:7, the prophet wrote of God: “I form the light, and create darkness; I make peace, and create evil; I am Jehovah, that doeth all these things.” On occasion, unbelievers appeal to this verse in an attempt to involve the Bible in a moral difficulty, since the text seems to suggest that God “created” evil. How should a Christian respond to such a charge?
First of all, the verse can have no reference to moral evil (wickedness) for such is opposed to the infinitely holy nature of God (Isaiah 6:3). Jehovah is a “God of faithfulness and without iniquity”(Deuteronomy 32:4). He is “not a God that hath pleasure in wickedness” (Psalm 5:4). Nor can it be supposed that this verse has to do with Jehovah’s original creation, for at the termination of the creation week, the Lord saw “everything that he had made, and, behold, it was very good” (Genesis 1:31).
The context of Isaiah 45:7, along with several passages of similar import, reveals the truth of the matter. Jehovah—through the prophet Isaiah—prophetically announced to King Cyrus of Persia (a century-and-a-half before the monarch’s birth!) His intention of using this pagan king as an instrument of His holy will. Within Isaiah 45:1-7 is a majestic affirmation of the universal sovereignty of the Almighty God; indeed, there is none like Him (vs. 5). He thus affirms: “I form light, and create darkness [i.e., control nature]; I make peace, and create evil [i.e., exercise control over the nations]; I am Jehovah that doeth all these things.”
