Isaiah 45:5-9
I form the light, and create darkness:
I make peace, and create evil:
I the Lord do all these things.
This verse has been tossed around before,
I make peace, and create evil. It is a difficult verse to properly understand and can, on the surface of the statement, come to the conclusion that God is the Author of evil, which He is not. Lets look at a few statements from great theologians....
John Gill....
"God is the author of, even of all prosperity of every kind, which this word includes: "evil" is also from him;
not the evil of sin; this is not to be found among the creatures God made;
this is of men, though suffered by the Lord, and overruled by him for good: but
the evil of punishment for sin, God's sore judgments, famine, pestilence, evil beasts, and the sword, or war, which latter may more especially be intended, as it is opposed to peace; this usually is the effect of sin; may be sometimes lawfully engaged in; whether on a good or bad foundation is permitted by God; moreover, all afflictions, adversities, and calamities, come under this name, and are of God." see Job_2:10,
John Calvin....
"
Making peace, and creating evil. By the words “light” and “darkness” he describes metaphorically not only peace and war; but adverse and prosperous events of any kind; and he extends the word peace, according to the custom of Hebrew writers, to all success and prosperity. This is made abundantly clear by the contrast; for he contrasts “peace” not only with war, but with adverse events of every sort.
Fanatics torture this word evil, as if God were the author of evil, that is, of sin; but it is very obvious how ridiculously they abuse this passage of the Prophet. This is sufficiently explained by the contrast, the parts of which must agree with each other; for he contrasts “peace” with “evil,” that is, with afflictions, wars, and other adverse occurrences. If he contrasted “righteousness” with “evil,” there would be some plausibility in their reasonings, but this is a manifest contrast of things that are opposite to each other. Consequently, we ought not to reject the ordinary distinction, that God is the author of the “evil” of punishment, but not of the “evil” of guilt."
Matthew Henry....
"I form the light, which is grateful and pleasing, and I create darkness, which is grievous and unpleasing. I make peace (put here for all good) and
I create evil, not the evil of sin (God is not the author of that), but the evil of punishment. I the Lord order, and direct, and do all these things."
As others have already noted, Satan is the author of the evil of sin, not God. As John Gill said, God suffers it. Even just simple reasoning, I could never attribute evil as a creation of my ever loving, gracious, Heavenly Father. Once He has finally dealt with the author of sin, Satan, and has thrown him into the lake of fire where he belongs, God creates a new Heaven and Earth with the New Jerusalem coming down out of Heaven where it is now, there will be an absence of evil and sin forever, never to re-appear....Praise Him Who is worthy of all praise from those whom He has rescued from the grips of sin and death. Praise the Holy One, Jehovah our Elohim, the Great I AM.
