James 4:13 Warning against Boasting.

13 Now listen to me, you that say," Today or tomorrow we will travel to certain city! Where we will stay a year and go into business and make a lot of money. " 14 You don't even know what your life tomorrow will be! You are like a Puff of smoke, which appear for a moment and then disappears. 15 What you should say is this;" If the Lord is willing, we will live and do this or that."all such boasting is wrong. 17 So then, those who do not do the good they know they should do are guilty of sin.
