In the Gospels (Mark, Matthew, and Luke), Jesus warns that "whoever causes one of the little ones who believe in him to sin, it would be better for him to have a great millstone put around his neck and be thrown into the sea." All parents must pay heed to this. In general, we must never be the cause for anyone to fall away from God. Parents in particular must always be good examples to their children. According to the Lord, any parent who causes one of his/her children to sin commits a grave sin indeed.
