From the first, it was not easy to be the mother of the Son of God. And now, even from the cross, Jesus is busy ripping apart families and breaking the hearts of mothers. Because he was obedient to the will of God, because Jesus did not waver from his God-ordained mission, he is a great pain to his family. “Woman, behold thy son.”
In that day, in that part of the world, there were no social attachments as rigid or determinative as that of the family. Family origin determined your whole life, your complete identity, your entire future. So one of the most countercultural, revolutionary acts of Jesus was his sustained attack upon the family.
