This thread has developed a very nasty tone.
I believe that parents should give their children guidance, and teach them critical thinking skills as well. Of course, a parent must HAVE critical thinking skills in order to teach them to their children.
Ahhh, there's the rub.
Kids are very perceptive. If we have disdain for a particular belief system, they will probably pick up on that disdain over the course of about 20 years of life in our house. Disdain is hard to hide. So is prejudice, and stupidity. For that matter, it's also hard to hide admiration.
Galatians 5:22-23
22But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23gentleness and self-control. Against such things there is no law.
If these attributes are present in our own lives, our kids will see them. They will want what we have, and will seek the source.
