We are supposed to have a Pollyanna sort of faith. Suppressed doubts fester and infect faith. Confronted doubt purifies faith from error.
Honest doubt is a new aspect of truth standing at our door, knocking for entrance into our lives.
In varying degrees, the combination of these is in different persons. Most people seem to avoid either extreme. They do not have conviction of faith to dedicate themselves to God exuberantly, and they are not sure enough of their doubts to enable them to be comfortable atheists. While many speak of believing in God, the shallowness of their conviction allows them to use God's name as a byword or to curse by. Even from my earliest remembrance, I had questions of doubt about religion, though I was not rebellious against it.
