Enjolras and Grantaire as an allegory

Enjolras in a way is like the guy who has been a believer for a while (probably since he was a little child) for him, his beliefs are so natural he does not understand disbelief.
Grantaire (obviously) is the non-believer who does not believe in anything, he is drawn to Enjolras who has the light of Christ in him (Grantaire also can have that if he just believes =P) Enjolras is put off a bit by Grantaire, but unknowingly his testimony is really attracting Grantaire.
When Enjolras is about to die and Grantaire is sober- it is like the darkness is lifted off him and he believes from that moment.
