Lack of supervision

From what I understand, you don't believe in private providence in our time (not ruling out exceptional cases, but you get the idea). In addition, you also claim not to know whether there is an afterlife, or what happens there. So, what's the deal with your belief?
You don't participate in most of the religious beliefs of Judaism, are quite skeptical, and don't support mysticism (at least from what I understand so far). So, what's the deal with your faith? Why aren't you simply a deist? What are your reasons for keeping the commandments, if you think God no longer intervenes and there may be no afterlife at all? I hope I'm understood.
