James 4:14

Boast not thyself of tomorrow; for thou knowest not what a day may bring forth.

Behold, now is the accepted time; behold, now is the day of salvation.—Yet a little while is the light with you. Walk while ye have the light, lest darkness come upon you: for he that walketh in darkness knoweth not whither he goeth. While ye have light, believe in the light, that ye may be the children of light.

What is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.

My days are swifter than a post: they flee away, they see no good. They are passed away as the swift ships: as the eagle that hasteth to the prey.—Thou carriest them away as with a flood; they are as a sleep . . . in the morning they are like grass which groweth up.

All the days of Methuselah were nine hundred sixty and nine years: and he died.

Let the brother of low degree rejoice in that he is exalted: but the rich, in that he is made low: because as the flower of the grass he shall pass away.
