Read James 4:14 Using Other Translations
Whereas ye know not what shall be on the morrow. For what is your life? It is even a vapour, that appeareth for a little time, and then vanisheth away.
yet you do not know what tomorrow will bring. What is your life? For you are a mist that appears for a little time and then vanishes.
How do you know what your life will be like tomorrow? Your life is like the morning fog—it’s here a little while, then it’s gone.
