“Try and think about the absence of God, and do realise that before you can knock at the door – and remember that it is not only at the door of the Kingdom understood in the general way, but that Christ really says ‘I am the door’ – before you knock at the door, you must realise that you are outside. If you spend your time imagining that in a mad way you are already in the kingdom of God, there is certainly no point in knocking at any door for it to be opened. Obviously, you must look round trying to see where are the angels and the saints, and where the mansion is which belongs to you, and when you see nothing but darkness or walls, you can quite legitimately find it surprising that Paradise is so unattractive. We must all realise that we are not yet in it, that we are still outsiders to the kingdom of God, and then ask ourselves ‘Where is the door and how does one knock at it?’”
