From his fifth Whitsun sermon:
There wants nothing now, O blessed Spirit, to go on and finish, but that thou shouldst come and order all our thoughts and spirits, that we may humbly receive the sound of thy holy word; that I, thy servant, may have utterance, this thy people give thee audience, all of us obedience, and all our hearts and tongues be so thoroughly heated with thy holy fire, that they may be filled with thy praise and honour all the day long!
And
Darkness cannot cover me, thick darkness cannot hide me, night itself cannot conceal me from thee, O thou divine Spirit! Oh keep me, therefore, that I may do nothing that may make me ashamed and hide myself, seeing thy eyes will quickly pierce into me!
