Great dream.
The setting of your dream provides another clue as to which part of your life the dream refers. As it is set at your father's workplace (a police station?), it may relate an issue at your work or in your career. Conversely, police/police stations in dreams are symbols of law and order, thus your sense that the dream is about your renewed faith may be apt.
Another thing to consider... while death in dreams often expresses feelings of change and transition in some area of your life, it can also reflect feelings separation... as a sense of separation in a relationship, perhaps with your father or maybe at work(?) As your father plays such an important role in your dream, it's worth considering.
Finally, fathers in dreams are not infrequently wisdom figures, but that is more often the case when the parent or grandparent is deceased. Still, your father's presence in your dream may reflect your sense of comfort, family, love and guidance through your "transformation" from your previous "haze" to the light of your new/renewed faith. Could there be any greater sense of revival than that for a believer?
Hope that proves helpful.
