James 4:13-17 - Arrogant Boasting About The Future
13 Come now, you who say, "Today or tomorrow we are going to such and such a town, to stay a year and go into business and make money," 14 when you do not know what your life will be like tomorrow! You are just a mist, which appears for a little while and then disappears.
15 This, instead of saying, "If it is the Lord's will, we shall live to do this or that." 16 But, as it is, you pride yourselves on your pretensions. All such pride is wrong. 17 So when a man knows what is right and fails to do it, he is guilty of sin.
