The reality is that we have no more authority over our children's hearts than we do our next door neighbor's or our office mate's. Now, if given the opportunity and liberty, we might indoctrinate them too. But I tend to think we find more pleasure and genuineness in seeing people come to belief rather than imposing belief on them. Oh, and no free-thinking adult would allow this sort of imposition, whereas our children have very little choice in the matter.
