Jee, how literally can you take text....
* An eternal life. Does the word heaven ring a bell?
* Death as a lake of fire and seperation from God. Again, does the word heaven ring a bell?
* Death as a punishment. We all die in the end but we wouldn't want to rush it would be? (except for omega perhaps ) Death is still a punishment even though life on earth is far from eternal.
And the last point. A world without death would be ridiculous. How can you eat a plant without killing it? What about overpopulation? Imagine the amount of mice there must have been in Eden if Adam and Eve didn't sin. Maybe it was a good thing they sinned. Life on earth would have been horrible by now if they hadn't....
