As a result, many of us entered the world with both an unparalleled level of conviction and a crippling lack of curiosity. So ready with the answers, we didn't know what the questions were anymore. So prepared to defend the faith, we missed the thrill of discovering it for ourselves. So convinced we had God right, it never occurred to us that we might be wrong.
In short, we never learned to doubt.
When we know how to make a distinction between our ideas about God and God himself, our faith remains safe when one of those ideas is seriously challenged. When we recognize that our theology is not the moon but rather a finger pointing at the moon, we can enjoy the freedom of questioning it from time to time. We can say, as Tennyson said,
Our little systems have their day;
They have their day and cease to be;
They are but broken lights of thee,
And thou, O Lord, art more than they.
