Nice copy/paste job. You're right, I do choose to believe in the revived animal sacrifice, simply because I read about it coming up again later. And yeah, Isaiah 65 isn't discussing temple activities. It's a different topic.
Try reading it with a bit of understanding. "The wolf and the lamb shall graze together; the lion shall eat straw like the ox, and dust shall be the serpent's food. They shall not hurt or destroy in all my holy mountain,” says the LORD."
Who shall not do the hurting or destroying? "They"
Whose the they? The animals.
In other words, the animals will neither hurt or destroy other animals. That's not discussing the temple sacrifice. Therefore, it's a different topic altogether.
