James (Jacob) 4:14-16

But you don’t have a clue what tomorrow may bring. For your fleeting life is but a warm breath of air that is visible in the cold only for a moment and then vanishes! Instead you should say, “Our tomorrows are in the Lord’s hands and if he is willing we will live life to its fullest and do this or that.” But here you are, boasting in your ignorance, for to be presumptuous about what you’ll do tomorrow is evil!
