Vanity of vanities, says the preacher, vanity of vanities! All is vanity. What is the profit to a man in all his labor which he labors under the sun? A generation passes away, and a generation comes; but the earth remains forever. The sun also arises, and the sun goes down, and hurries to its place where it arose. The wind goes toward the south, and it turns around to the north; it whirls around continually; and the wind returns on its circuits. All the rivers run into the sea; yet the sea is not full; to the place from where the rivers come, there they return again. All things are full of labor; man cannot utter it; the eye is not satisfied with seeing, nor the ear filled with hearing. That which has been is that which shall be; and that which has been done is that which shall be done; and there is nothing new under the sun (Ecc. 1:2-9).

Surely you know that many runners take part in a race, but only one of them wins the prize. Run, then, in such a way as to win the prize. Every athlete in training submits to strict discipline, in order to be crowned with a wreath that will not last; but we do it for one that will last forever. That is why I run straight for the finish line; that is why I am like a boxer who does not waste his punches. I harden my body with blows and bring it under complete control, to keep myself from being disqualified after having called others to the contest (1 Cor. 9:25-27).

For God so loved the world that He gave His only-begotten Son, that whoever believes in Him should not perish but have everlasting life. For God did not send His Son into the world to condemn the world, but so that the world might be saved through Him (John 3:16, 17).
