He tried to give men good instructions as to what Kind of creatures to consider as Food and the Chinese ignored him. What is He supposed to do? He is not responsible for what the Chinese did.
Came from men being in contact with "exotic" creatures they were never meant to touch.
Then you have no answer to give to anyone and the god you believe in is simply cruel. It is better to believe that God is who He describes himself to be than the above version. If you stick to the above, you have no answer to anything cruel or Evil that happens in the world because you have already decided God's will decrees that which He hates. Makes no sense but that is not my theology or my Problem. I believe He is sovereign as He describes his sovereignity to be. The above is not it.
It is good to trust God but blind trust is not as good as understanding God.
God does use Evil to good but only for those who
1. love Him according to Him, not us
2. are also called according to His purposes
If a Person does not fulfill that criteria, then He is not working Evil to good for them necessarily. He might but most often does not. They do not fulfill the criteria.
I can assure you that God has revealed His ways and Himself to a greater degree than most experience, especially if they believe God is the author of Evil in the world in some form. There are even more strict requirements on those to whom God reveals Himself in this greater degree. One is not believing He is the author of evil. Anyone who does not believe GOd is good and only does good will not find God show them anything of himself. This lets out a whole branch of Christians who believe God does evil and are OK with that theology.
So if you want my advise or you want to understand God, you will need to drop the idea that He is controlling everything and everyone on the planet. Without dropping that, you will learn nothing of the ways of God. Do you want scripture for this?
