God did not create lions to eat meat. In Genesis 1:30 it says he created the animals to eat vegetation of the ground. And it says in Isaiah 65:25 that lions will eat straw like the ox. So it was never God’s intention for animals to eat each other. The world fell from grace when we stopped following God’s instructions and it will be restored again when we go back to living according to his ways. What is lacking is faith in God and trusting in his ways.
