For God to prove himself on demand, physically, would be a grave disappointment, and the strongest Christians should be considerably grateful that he chooses not to do so. The skeptic endlessly demands proof, yet God refuses to insult the true intelligence of man, the '6th sense', the chief quality, the acumen which distinguishes man from the rest of creation, faith.
The human spirit is your specifically human dimension and contains abilities other creatures do not have. Every human is spiritual; in fact, spirit is the essence of being human.

To divide one's life by years is of course to tumble into a trap set by our own arithmetic. The calendar consents to carry on its dull wall-existence by the arbitrary timetables we have drawn up in consultation with those permanent commuters, Earth and Sun.

... I remember you and recall you without effort, without exercise of will; that is, by natural impulse, indicated by a sense of duty, or of obligation. And that, I take it, is the only sort of remembering worth the having. When we think of friends, and call their faces out of the shadows, and their voices out of the echoes that faint along the corridors of memory, and do it without knowing why save that we love to do it, we content ourselves that friendship is a Reality, and not a Fancy -- that it is built upon a rock, and not upon the sands that dissolve away with the ebbing tides and carry their monuments with them.
Anyone who can be proved to be a seditious person is an outlaw before God and the emperor; and whoever is the first to put him to death does right and well. Therefore let everyone who can, smite, slay and stab, secretly or openly, remembering that nothing can be more poisonous, hurtful, or devilish than a rebel.
