Men in general tend to see the big picture. Moms sweat the details. That is why God intended that a family be comprised of one husband and one wife who have children TOGETHER, so that those children, male and female, will have the best possible environment in which to grow up.
Fathers most often provide the discipline; mothers provide the nuruturing.
That isn't to say mothers can't discipline (mine sure could) or that fathers can't nurture (I think I'm not half bad at that with my own daughter), but their various strengths compliment one another in the rearing of children.
BTW, I've been on both sides of the fence. My first marriage ended in divorce when my first wife decided "life was passing her by" and took her "friends'" advice to "get rid of the jerk" (defined as "any male").
So I was pretty much shut out of their upbringing.
I remarried "on the rebound" as they say, a very ill-advised decision that also ended in divorce within a few years. But this time, I got custody of my daughter from that marriage, and have been rearing her ever since.
I think I've done well as a parent for my kid, and although my present (and future) wife pitches in a great deal, my daughter still looks to me as the primary parent.
She loves her mother, and visits her when she can, but she would rather be with me, where she feels "safe".
Her mother reared four older sons, two of whom are in jail now, and all of whom have police records. The woman NEVER COULD discipline worth a hoot.
I would say that even within the church most fathers are not doing the disciplining. It's just not happening. Most fathers come home and want to be buddies to their kids, but don't want to discipline. That's what I see, anyway. My husband was the same way, but has finally matured into a disciplinarian. Good parenting--all around--is in decline. It's not just the single mothers. I see A LOT of out of control kids in the schools around here, and most of them have parents.
