If you want to clone your child because he or she is dying, you are just avoiding the grief that would follow the child's death. But death and grieving are natural and should not be removed from our lives. I have a cute little dog named Spot. But she's getting old, and I've thought a lot about getting her cloned before she dies, because she's not a breed, she's a mutt, and I'll never be able to find another dog like her. As a biology teacher and a religious person, I don't have any problems with cloning.
Identical twins are basically clones of each other.
I think that if our Heavenly Father had a problem with cloning, He would never have allowed identical twins to become a reality. Even identical twins aren't totally identical. They are individuals. So let's not ban this technology like a bunch of book-burning Nazis. There is no sense in banning something with so much potential because we're afraid of clone maniacs.
