Submission to Baha'u'llah's commandments is very much Baha'i submission, perhaps you accidentally included this quote in your OP;
"True liberty consisteth in man's submission unto My commandments"~Baha'u'llah?
As for liberty in the free world, the law of the land based on rational legal processes seems sufficient. I don't see commandments as having anything to do with it.
In my opinion.
It is obvious that humanity at the current time will not choose this option, so the important thing to note in this OP is that this in not directed at the Baha'i Faith, but at a conversation as to what is a productive and useful "Liberty".
I used that quote as a guide, not as the direction of this OP.
That submission is found in all Faiths.
So do how do you see Liberty?
