Suppose I am writing a novel. I write 'Mary laid down her work; next moment came a knock at the door!' For Mary who has to live in the imaginary time of my story there is no interval between putting down the work and hearing the knock. But I, who am Mary's maker, do not live in that imaginary time at all. Between writing the first half of that sentence and the second, I might sit down for three hours and think steadily about Mary. I could think about Mary as if she were the only character in the book and for as long as I pleased, and the hours I spent in doing so would not appear in Mary's time (the time inside the story)at all...God, I believe, does not live in a Time-series (the real one)at all. His life is not dribbled out moment by moment like ours: with Him it is, so to speak, still 1920 and already 1960. For His life is Himself.
If you picture Time as a straight line along which we have to travel, then you must picture God as the whole page on which the line is drawn. We come to the points of the line one by one: we have to leave A behind before we get to B, and cannot reach C until we leave B behind. God, from about or outside or all round, contains the whole line, and sees it all... what we call "tomorrow" is visible to Him in just the same way as what we call "today." All the days are "Now" for Him. He does not remember you doing things yesterday; He simply sees you doing them, because, though you have lost yesterday. He has not. He does not "foresee" you doing things tomorrow; He simply sees you doing them: because, though tomorrow is not yet there for you, it is for Him.
