James 4:4-15 (New International Version)

 ⁴You adulterous people, don't you know that friendship with the world is hatred toward God? Anyone who chooses to be a friend of the world becomes an enemy of God. ⁵Or do you think Scripture says without reason that the spirit he caused to live in us envies intensely?^{[a] 6}But he gives us more grace. That is why Scripture says:
   "God opposes the proud
      but gives grace to the humble."^[b]

 ⁷Submit yourselves, then, to God. Resist the devil, and he will flee from you. ⁸Come near to God and he will come near to you. Wash your hands, you sinners, and purify your hearts, you double-minded. ⁹Grieve, mourn and wail. Change your laughter to mourning and your joy to gloom. ¹⁰Humble yourselves before the Lord, and he will lift you up.

 ¹¹Brothers, do not slander one another. Anyone who speaks against his brother or judges him speaks against the law and judges it. When you judge the law, you are not keeping it, but sitting in judgment on it. ¹²There is only one Lawgiver and Judge, the one who is able to save and destroy. But you—who are you to judge your neighbor?

Boasting About Tomorrow

 ¹³Now listen, you who say, "Today or tomorrow we will go to this or that city, spend a year there, carry on business and make money." ¹⁴Why, you do not even know what will happen tomorrow. What is your life? You are a mist that appears for a little while and then vanishes. ¹⁵Instead, you ought to say, "If it is the Lord's will, we will live and do this or that."
