William Gurnall (1616-1679)
When thou prayest before others, observe on what thou bestowest thy chief care and zeal, whether in the externals or internals of prayer, that which is exposed to the eye and ear of men, or that which should be prepared for the eye and ear of God; the devout posture of thy body, or the inward devotion of thy soul; the pomp of thy words or the power of thy faith; the agitation of thy bodily spirits in the vehemency of thy voice, or the fervency of thy spirit in heartbreaking affections. These inward workings of the soul in prayer, are the very soul of prayer.
William Gurnall (1616-1679)
