Ian Ker, John Henry Newman: A Biography (Oxford & New York: Oxford U. Press, 1988, 2009) ("Newman wrote 'the Pillar of the Cloud', better known by its opening words, 'Lead, Kindly Light'. [] But the words which are most characteristic of Newman come at the end of the first stanza:
'I do not ask to see/ The distant scene, --one step enough for me'. It was a thought which was always to be at the heart of his spirituality, namely, that light is only given to us gradually bit by bit, but that we are always given enough to see what we have to do next, and that when we have taken that step which been lit up for us, we shall see the next, but only the next, step illuminated--while to attempt to see several steps ahead or the end of the path is not only futile but also self-defeating." Id. at 79-80.).
