Upright, meek, humble, and heavenly minds, then, must the ambassadors of this great King have, and so obtain His intimacy, mounting upon those wings of prayer and meditation, and having the eye of faith upwards. Thus shall they learn more of His choice mysteries in one hour, than by many days poring upon casuists and schoolmen, and such like. This ought to be done, I confess; but above all, the other must not be omitted. Their chief study should be, that of their commission, the holy scriptures. The way to speak skilfully from God, is often to hear Him speak.
Robert Leighton (Archbishop of Glasgow, 1611 – 1684)
