Let's turn to scripture and see what we find. First, we have to look at the creation stories, since that's where we find the accounts of animals being created. Okay, people have souls. And apparently so do the rest of the animals. Well, eating animals certainly wasn't in the original divine plan.
Animals have personalities.
They apparently have souls. And they weren't created for our dining pleasure. The Bible isn't big on telling us what heaven's like. The word picture in Revelation 21 often used to describe heaven actually describes the new earth and the new Jerusalem. So says scripture.
