When you're a child or a teenager, the tendency is to look at your father as a bit of a pain in the neck. But as you grow up, have a career, get married and have a family of your own and face the daily pressures of life as a father, you quickly realize that your father was much smarter, much wiser and much greater than you used to give him credit for.
If we think our tradition demands we risk our children's lives by not accepting them, like Avraham, maybe we are misreading our tradition. God does not need our defense, and God will most certainly be there when we get back. All our children are angels who are just waiting to be welcomed into the tent.
