Dear iouae,
Okay, you are done talking with 6days, so I would like to help you. See in Gen. 1:30KJV. "And to every beast of the Earth, and to every fowl of the air, and to every thing that creepeth upon the Earth, wherein there is life, I have given every green herb for meat; and it was so." In other words, ALL of God's creatures and Man were given plant life and fruit to eat. Lions did not eat lambs. They ate grass or straw. It does say in the Bible later on that the lion shall eat straw like the lamb, or something to that effect, after Armageddon is over. It shall most likely be again, that man will eat plant life and fruit, and all creatures also will be vegans. Eating meat will not happen, but only according to what God's Will is about it. I also believe that some people shall live again until 900+ years again. The devil shall be bound with chains and locked up for a thousand years. See Rev. 20:2,3KJV. From what I understand, the devil also causes death, but he will be locked away for 1,000 years, so there will be no devil to cause death. Man shall live only as long as God strives with him to keep him alive. That's all for now.
May God Guide You Towards The Truth,
Michael
