If I understand your question, I would say Luke 11:1-13 refers to asking for the Holy Spirit (Luke 11:13). Luke 13:25 seems to refer to something like the judgment. Luke 11:1-13 is Jesus response to the disciples' desire to learn how to pray. And Jesus's basic reply is, if you ask for the Spirit, God will give you the Spirit. Luke 13:25 is in response to the question, "Lord, will only a few be saved?" Saved from what? I assume the judgment. Does that help?
He uses the same type metaphor, but different references. Or, I completely misunderstood the question.
