Remind me hoe brief my time on earth will be. Remind me my hours are numbered, and that my life is fleeing away.

To make the best use of your life, you must never forget 2 truths: first, compared with eternity, life is extremely brief. Second, earth is a temporary residence, you wont here too long, so dont get too attached.

Alien,pilgrim, foreigner, stranger, visitor,and traveller……

So we ix our eyes not on what is seen, but on what is unseen. For what is seen is temporary, but what is unseen is eternal.
