Yes, you guard and protect the Torah, but it does not guard or protect you, because, once mature, you leave aside the things of the child, such as the tutor. Jesus, the living Spirit guards and tutors me now.
How would it look if you grew up to manhood, but your tutor kept following you around trying to teach you how to get by, when you already know? Wouldn't you say to the tutor, thank you, but I have grown up now, I can walk and live and work as a man, not a child.
I believe it does, but not in the sense I see you writing in.
Since I am no longer under the tutor, yes, that tutor no longer outwardly guards or protects me. What the tutor has taught though, that guards and protects me. You yourself said it, that Yeshua guards and protects, for he is the goal of Torah, just as the goal of a child under a tutor would have been to learn from them and safely reach manhood. Manhood is the goal.
I will use this example from my own life to see if it helps, that you will understand where I am coming from.
I took up a medical assistant trade while in the military. The tutor, my instructor, taught me what I need to know, including how to do my job safely by keeping within the parameters of what I was to do. When I graduated, I was no longer under that tutor, but what he left me stayed on, continuing to guard and protect me (for example, I knew how to dispose of a used needle so as not to stick myself or others). I applied that practice in the way I was taught, and so was guarding and protecting the medical assistant field as well.
So yes, if my tutor followed me around when I was working and trying to continue showing me what to do, I would certainly respond as you did. I left that tutor, but not what the tutor has taught me.
I see it working that way in every situation. We all had parents, who tutored us into adulthood, and even though we are no longer under their tutelage as when children, what they taught us stays with us, guarding and protecting us. As I live according to what they taught me as a child, I am then guarding and protecting my adulthood. That is the sense in which I mean it.
As Paul, who was also no longer under the tutorship of the Torah, I too, rejoice in the Torah according to my inner man, and am a servant of it.
For I rejoice in the Torah of Alaha, in the interior man.
(Rom 7:26) Now, therefore, in my conscience, I am a servant of the Torah of Alaha; but in my flesh, I am a servant of the law of sin.
That tutor led me to Messiah, and in so doing, also taught me the reality that as long as I try to observe Torah in my flesh, it will only awaken sin within my members to kill me again and again. The Torah does not reside in my flesh, but in my inner man, the heart, conscience.
No, I am not referring to a bunch of do's and don'ts, but of the realities of God's very nature and character, expressed in his Dabar, living within each and every one of us. That is the Torah he said he would place in the heart, which he did when he came to take up residence in us.
