No one said anything about enrolling.
As for the rest of your statements, Baha'u'llah clearly disagrees with you:
"The first duty prescribed by God for His servants is the recognition of Him Who is the Dayspring of His Revelation and the Fountain of His laws, Who representeth the Godhead in both the Kingdom of His Cause and the world of creation. Whoso achieveth this duty hath attained unto all good; and whoso is deprived thereof hath gone astray, though he be the author of every righteous deed. It behoveth every one who reacheth this most sublime station, this summit of transcendent glory, to observe every ordinance of Him Who is the Desire of the world. These twin duties are inseparable. Neither is acceptable without the other. Thus hath it been decreed by Him Who is the Source of Divine inspiration." (Aqdas, verse 1)
It's clear that you have to first recognize Baha'u'llah, then do whatever he says. And these two duties are not separable or else you are considered astray even if you perform every righteous deed.
The thing about religion is, everyone "gets" it at their own level, according to their capacity. For me, the first paragraph of the Aqdas that you have quoted here is about the religious value of "works" (the ones the Aqdas goes on to prescribe, such as prayer, fasting, pilgrimmage, inheritance, marriage, divorce, tithes (huququllah) and so forth). It says that "good works" (such as these) do not have religious merit unless they are based on "recognition" (`erfaan). `Erfaan is the consciousness born of a mystic encounter with the divine, it is sometimes translated as gnostic knowing.
The context is that Bahais from Islamic backgrounds have been pestering Baha'u'llah for some years for a book of laws they can follow, to replace the Islamic Shariah code and the Bab's Bayanic law. Eventually Baha'u'llah agrees, and compiles and composes the Aqdas (some of its contents already existed in other works), but he begins by saying (my paraphrase) you can pray and fast all you like, but if you don't have `erfaan in your heart it's not worth a bean, as a way of pleasing the Beloved.
Christianity has the same concept, in the form of the much-disputed relationship between faith and works. The Bahai approach is like the Catholic one: first faith, then good works. In Islam this is the doctrine of intention/neyyat, which says that each good work (prayer, but also charity) has religious value only if it is preceded by the correct intention. One has to form the intention, I am going to pray the salat as Muhammad and Islam has taught me, and then begin the prayer, in order to have obeyed the law of praying. (the salat is the 5-times per day obligatory prayer).
Naturally you can understand that first paragraph in other ways, as you wish. My reading is shaped by reading the Arabic, and knowing the Islamic context of the terms Baha'u'llah uses there.
