Of what purpose is a soul to a lizard if it cannot be saved?
By wanton destruction of everything God gave us, we demean God's Creation on a daily basis.
Wanton destruction? Do you mean as in killing pigs for bacon and pork chops? Are you a vegetarian? Do you wear leather shoes? Do you use a checkbook and read paperbacks which are produced by cutting down living trees?
All living things have a soul.
Does a tree have a soul? A weed? Compost?
You are confusing it with something esle. All living things have "life" in them. When they die, "life" leaves them, i.e. their "soul" separates; they stop breathing, they stop "living" and become dead. That goes for all living things. I know this is all Greek to you, and in fact it is Greek! :)
