so...I do want to say that Timber's comment is hugely insensetive and self-righteous, and does not strike me as a remotely christian thing to say.
That said, however, I would also like to point out two things: the first is that putting God first and taking decent care of your kids are not mutually exclusive. Kids do not have to be the center of your entire life to be well raised. In fact they're probably better off if they're not the center of your life: it will make them more independent and you less likely to get burnt out.
The second is that, while I definitely think Vyckie's previous life was seriously unhealthy, I don't think her problem was that she was putting God first; I think her problem was her abusive husband and her fundie church. Having multiple children and submitting to your husband do come up in the bible, but they are not a significant theme in the gospels. The former shows up mostly in the psalms and the histories, and seems to be primarily cultural (having lots of children is much more valuable in low tech cultures.) The latter is primarily discussed in the letters of Paul (which many Christians consider to carry less weight than other books of the bible, since Paul never knew Jesus while he was alive, and was primarily interested in evangelism, rather than doctrinal purity.) Homeschooling, and homebirthing (and home everything else-ing) are not biblically mandated (sure they existed, but only because the alternatives didn't,) and working yourself to death is seen as actively bad (as shown by the recognition of a need for a day of rest, or the story of Mary and Martha.)
Again, I'm definitely not saying that you should have to make everything about God and ignore your children until they attempt suicide. But I do think that Vyckie's problems were related more to abuse, and to fundamentalism specifically than Christianity generally.
