If you never questioned your beliefs, - you are just a puppet dancing to somebody's strings. If God had wanted your mindless obedience, you would've been created without mind and without free will.

But you have both so you can come to God of your own accord. Just look at the lives of saints, - most of them had gone through a dark night of the soul, and that's why their faith was so strong.

The path to true faith always goes through doubt. So ask those questions you've always been afraid to ask, and find the answers, and then your faith will become unshakable.
