It’s OK to question. Without questioning there can be no progress. If something seems impossible it is alright to have some confirmation. However, even scripture, tradition, reason, and experience may not be enough. Sometimes our faith in them is good . Sometimes not so much. We need to be open to new information, or reasoning etc.
