Ray Bradbury on Life's Purpose

Ray Bradbury in his essay, "Mars: Too soon from the Cave, Too far from the Stars," meditates on Man's purpose in the universe.

We are representatives of the Life Force. our hidden genetics propel us up, upward, and out. We cannot resist the impulse to footprint Mars as we did the Moon. And when we arrive there, what shall we say to the mysterious mothering universe? "We are here! Behold, we have cast our seed upon a windless wind in a lonely place that we shall make less lonely. Do we rest now?" To which the Cosmic response must be, "No." There can be no rest, but always moving on. For to rest means to stop, and to stop might well mean a fall back into the dust. In the words of the Cabal at the end of Things to Come, "Which shall it be?" The stars or the grave? It is a million-year journey. Sleepless at dawn, arise and go.

Bradbury (2000). According to Bradbury, there is no rest for mankind. However, the bible says differently.

Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. (Hebrews 4:11 ESV)

We, as Christians, must strive to enter the rest that Christ has provided for us through His death on the Cross. We, at the end of the age, will enter that rest and be in the presence of God along with other believers and the angelic host. We do not strive to find meaning, but we strive to find rest.
