James 4:13-17 - Arrogant Boasting About The Future
13 Come now, ye that say, Today and tomorrow we will go into such a city, and spend a year there and traffic, and get gain, 14 (whereas ye know not what will be on the morrow; for what is your life? Ye are even a vapor, that appeareth for a little time, and then vanisheth away;)
15 instead of saying, If the Lord will, we shall both live and do this or that; 16 but now ye glory in your boastings. All such glorying is evil. 17 Therefore to him that knoweth how to do good, and doeth it not, to him it is sin.
