After Christ had put God’s willingness to answer prayer in a very clear and strong light, he then urges to importunity, and that every unanswered prayer, instead of abating our pressure should only increase intensity and energy. If asking does not get, let asking pass into the settled attitude and spirit of seeking. If seeking does not secure the answer, let seeking pass on to the more energetic and clamorous plea of knocking. We must persevere till we get it. No failure here if our faith does not break down.
