 No question or level of doubt could ever cause God to crumble. God is really great at being God. The same yesterday, today, and forever. We are free to ask him questions because we can rest assured that God is God. And another reason why God wants us to ask questions why it's okay, even Jesus asked questions. If Jesus demonstrated humanity at its best as God originally intended, it would make sense that we follow his example and even Jesus asked questions of God.
