Another question why did God create a devil? [1]

The Answer:

Our Lord God didn’t create a devil. He created an angel and the angel transferred himself to be a devil. That means the devil when he was created, he was not a devil. God created and so that everything is good. We read about the fall of the devil. And the prophecy of Isaiah chapter 14. And the prophecy of Ezekiel chapter 28. I’ll give you an example about what was the devil. Ezekiel chapter 28. From verse 14. “You were the anointed. You were perfect in your ways from the day you were created. You were the seal of perfection that above the devil. You were the seal of perfection full of wisdom and perfect in beauty”. He was one of the cherubim of the cherubim. One of the great angels of God. When he was created. Then it is wrong to say that God created him as a devil. He created him as a great angel one of the cherubim. He was the seal of perfection of beauty. But he changed himself from an angel to be a devil. This is about the devil.
