Why would any parents subject their family to such publicity and therefore scrutiny? Especially knowing there was such an explosive skeleton in the closet.Their model in family-rearing is sheltering. How ironic is it to shelter your children, but then expose them deliberately for all the world to see.
This link to a Gospel Coalition article, about both the Duggars and sheltering, is extremely instructive. So many Christians are bound up in the pride and the untruth of "If we protect our children, they will be OK." - as well as "If I protect myself, I will be OK." That ignores the flagrant sin in our hearts, and in our children's hearts. I will not be OK just because I am careful. Neither will my children. Oh that we would grasp the depth of sinfulness in our own hearts.
