There is a difference between omniscience and a decree.
God created man with a free will to choose good and evil. He desired man to choose good. He tested him in the garden. Man failed, and chose evil. God did not decree evil. Man chose evil. There is the difference which you fail to see, and consequently blame the evil on God.
God desires that all men be saved.
God is not willing that any should perish but that all should come to repentance.
But he has given man his own choice that he may come to repentance and be saved. He doesn't force him; man is not a robot. He is made in the image and likeness of God. And unlike the animals is given a free will, the ability to reason, and choose between good and evil.
So God never intended for man to fall???
Was it a surprise?
Why is "free will" so important to God that he was willing to let billions upon billions upon billions upon billions pour into hell from this earth like grain from a great hopper where they will roast in unimaginable agony forever and ever and ever and ever without so much as one SECOND of relief?????
Why do you think this makes God MORE loving??????
How do you think this makes him LESS the author of evil???
Did he not make the universe knowing that if he made it that way the result would be that multiplied BILLIONS would fry in hell forever?
Could he NOT have made a world where man would NOT fall??
What is so PRECIOUS to you and in your mind, to GOD, about free will that it was well worth the price of unspeakable eternal torment of so many billions of men, women, boys and girls?
