James (Jacob) 4:12-17

There is only one true Lawgiver and Judge, the One who has the power to save and destroy—so who do you think you are to judge your neighbor? Listen, those of you who are boasting, “Today or tomorrow we’ll go to another city and spend some time and go into business and make heaps of profit!” 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! So if you know of an opportunity to do the right thing today, yet you refrain from doing it, you’re guilty of sin.
