James 4 · a question people ask
"Come now, you who say, “Today or tomorrow let’s go into this city and spend a year there, trade, and make a profit.”" (4:13). Does the letter say it's wrong to make plans?
From those words the letter goes on to "Yet you don’t know what your life will be like tomorrow." (4:14), then "For you ought to say, “If the Lord wills, we will both live, and do this or that.”" (4:15), and then "But now you glory in your boasting. All such boasting is evil." (4:16). These notes say no more than these verses say.
The verses
“Come now, you who say, “Today or tomorrow let’s go into this city and spend a year there, trade, and make a profit.” Yet you don’t know what your life will be like tomorrow. For what is your life? For you are a vapor that appears for a little time and then vanishes away. For you ought to say, “If the Lord wills, we will both live, and do this or that.” But now you glory in your boasting. All such boasting is evil.”
