"But with unhurrying chase, And unperturbed pace, Deliberate speed, majestic instancy, They beat -- and a Voice beat More instant than the Feet -- 'All things betray thee, who betrayest Me'"

-- "The Hound of Heaven."

"Behold, I stand at the door and knock: if any man hear my voice and open the door, I will come in to him, and will sup with him, and he with me."

-- Rev. iii.20.
