Discern between things visible and spiritual

Grant me, O Lord, to know what I ought to know, to love what I ought to love, to praise what delights Thee most, to value what is precious in Thy sight, to hate what is offensive to Thee. Do not suffer me to judge according to the sight of my eyes, nor to pass sentence according to the hearing of the ears of ignorant people; but to discern with a true judgment between things visible and spiritual, and above all, always to inquire what is the good pleasure of Thy will.
