I think Jesus was (rightly -- duh) saying cautioning all of us against thinking that we were somehow less called, less blessed, less whatever than anybody who had a blood relationship to Him.
It seems so silly to say this big duh, but Jesus was an AWESOME spiritual teacher. HE pierced to the division of bone and marrow, fer shur! And anyone whose pious outcry has a hint of "poor li'l ol me" (with the underburden of "So I don't have to try real hard because I'll never have the special advantages of somebody else") Jesus would skewer in a heartbeat.
We all are given grace to hear and keep the word of God (unless we believe in double predestination), so we can't go back to our self-pity and inertia.
I preached on this. How come I don't get to be immaculately conceived and all that? it's not FAYur!
Short answer: mary has her vocation and I have mine. Mine suits me to a T. I compared the whole thing to wondering why I don't get to wear Tony lama boots just because they're not in my size. And then, when I find a pair of boots that FIT .... (I have weird feet) it's WONDERFUL! I don't want to wear Mary's vocation. I want to wear the one God set apart for ME! I feel good, I look good, I can do good because I'm wearing MY boots, not hers.
Not logical from the Scripture.
The EMPHASIS was on
HEARING AND DOING The Word.
Period.
