“To understand it [heaven], let us skip all approximations and go straight to the point: Heaven is the intimate reserve of holy God, that which St. Paul calls the “light inaccessible” which he inhabits, unapproachable for any creature (I Tim. 6:16). When we meet a person in the street or in a room, he stand there openly before us. We can look at him, photograph him, describe him, and can often guess a good deal of what is going on inside him. Withal, he is more or less ‘public.’ On one point, however, he remains impenetrable: his attitude towards himself, his manner of answering for himself and his acts. For the most part, man is absorbed by corporal, psychological, sociological realities; in other words, by public things. But there are certain moments when he retires into a corner of his being that is closed to others–into his most personal self. No one can violate that privacy; if it is to be opened, then only by opening itself. This is what happens in love, when a person not only permits himself to be observed, not only speaks about himself, but gives himself in vital exchange. If the other accepts him, likewise opening the way to his most intimate self, desire the other more than himself, entering into pure contemplation and exchange, the the two intimacies unite in a single community open to both participants, but closed to everyone else. The greater and deeper the person and his experience, the less accessible this inmost realm will be. But what if it is not question of a person, but of God? God, the incommensurable, infinite, simple; essence of truth and holiness? His reserve is absolute. Nothing can even approach it. God is all light because he is Truth itself; all clarity, because nothing can overshadow him; he is the Lord, free and genuine Being to whom all that is belongs–yet inaccessible in his light, mysterious in his truth, invulnerable in his kingdom. This initmate reserve of God is heaven, ‘destination’ of the risen Lord–and not only of his spirit, but of the whole resurrected Lord in all his living reality” (Romano Guardini, The Lord, p 429).
