Scientific measurements indicate that we are moving even when we are standing still. The surface of the earth at the equator rotates at about 1,000 miles per hour. The earth is orbiting the sun at about 67,000 miles per hour. Our solar system whirls around the center of our galaxy at 490,000 miles per hour, and it zooms along at 43,000 miles per hour in the direction of the star Vega in the constellation Lyra. But that's not all. Our Milky Way galaxy is hurtling through space at 1.3 million miles per hour.

A man lying on his back in a quiet park on a cloudless summer day may feel as though all time and movement have stopped under the hot rays of a noonday sun. But the scientist and the godly person know otherwise. Just as we are hurtling through the heavens at unimaginable speeds, so too we are moving from here to eternity. Our days and opportunities to live for the Lord pass so rapidly that we cannot afford to waste any of them.

The psalmist prayed, "Teach us to number our days, that we may gain a heart of wisdom" (Psalm 90:12).
