The Law is spiritual in this way:
The things you do in the physical, for example, abstain from swine, love your neighbor and your enemy(not the most high’s enemy like satan), and love the Father with everything you’ve got, these things help you and those around you stay healthy, safe and on par with the most high. And on the spiritual side of things keeping the commandment causes the mind to rule over the flesh and not the other way around. We war against spiritual wickedness that wants the flesh to subdue the mind because this wickedness can always tempt the flesh with all the pleasures it possesses.
So to state clearly, the flesh is subdued by the mind with the Law because the Law (if kept) does not allow the flesh free rain. That is the spiritual understanding that comes when the physical is performed meaning you actually do the commandments.
Why do I not eat swine? That is because it’s nature is very filthy. Then also, this teaches me that people who’s nature is the same as swine, I am to avoid also.
The spiritual is the teaching of the soul ruling over the flesh.
Because your flesh isn’t of The Most High your Ruach(Spirit) is. So it’s your Ruach that is master of the Law not your physical, which is subject to the Law. Your Ruach must learn to put your physical under submission. So many people lack understanding of this and therefore when they read the law they think it’s a physical matter. For example, when people hear “Thou shall not kill” they think it literally means slaying someone with a weapon although The Most High have given plenty orders to kill, but people never consider that the Kill that’s being spoken of is this “Thou shall not Kill someone’s soul” when people lead people astray from the Truth its spiritual murder. The MessiYah’s earthly walk was to show that the Law is a spiritual matter.
The natural order of our very creation is that the mind, namely the soul, is the dominant ruler within us but because of sin the flesh acts out and usurps the soul and rules the majority of what little life we have. We are dominated by our very own passion: money, sex, drugs, tv , games, social media, and whatever else Satan knows can tempt us and distract us. But if we keep the law and remained occupied in it all of these things would be kept at bay while the mind rules.
The five senses, are they not just sending info to the Brian where reason dwells? That is there job. That’s all they should be allowed to do, send information but we think with our senses, this is an abomination to us. We see it, it looks good, therefore we want it without having truly put it to the test which can only be done with reason of the mind.
Mind(reason/soul) over Matter(flesh/material)
