The Lord’s Prayer is the authentication, the signature, the demonstrating formula of all his teaching; it is the master-recipe for producing his demands, for reproducing his acts, for adopting not only his method but, if we will make the system our life, his nature. Here, in epitome are the essential means and ends of his faith. Here is the practice, the exercise, whereby he was able to call himself the Son of Man, at last Man as God wills, and to call us through the same exercise and practice to rise to such sonship. By this prayer we may and must judge all Christianity, whether it is the millennial record of the Church or our own acts and thoughts of the last half-hour.
