The day when you have it all figured out may never come.
To me, the very point of faith (or belief) is doing what you feel like doing -- acting on the "measure of faith" you may have at any moment, without wondering too much if it makes sense, or if it will make sense "in the end".
Prayer, for instance, is logically inconsistent for who doesn't really believe in a personal god; it is inconsistent, too, for the dogmatic believer who thinks God knows and has already "planned" everything, whether he prays or not. Yet both may feel like praying. Why would they not allow themselves to do it? For the sake of consistency?
When I exited the JWs and after that, I often experienced what I might call provisional belief -- feeling that I did believe something for the moment being but doubting I would still be able to believe it the next day. I often chose to act on what I happened to "believe," while not trying to retain belief anymore that it would remain. Instead of waiting until you're sure of the right path before beginning to walk, walking while you can and find out you have made your own path.
Walk while you have the light, so that the darkness may not overtake you.... While you have the light, believe in the light, so that you may become children of light.
If belief has anything to do with children, it may be all about playing.
