Clark,

You yanked this passage completely out of it's context!!!

The Bible does not tell parents to stone their children. You are quoting part of the "law" that was given specifically to Jews (no one else) during a specific time for a specific reason.
We do not live by the 10 commandments today, although it is still wrong to lie ,steal, or murder and so on. The Jews were under the law as a means of their salvation. Any disobedience could only be atoned with blood only, this is the reason for all the sacrifices.

We no longer depend on obedience to the law for our salvation. Christs' sacrifice was final, and was for all the sins of the world.
