Of course, this is open to interpretation by others besides Calvin, especially if I were to include verse 17 * , which I didn’t, because it would have spoiled Calvin’s fun.
Now 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.’ Why, 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. Instead, you ought to say, ‘If it is the Lord’s will, we will live and do this or that.'” — James 4:13-15
* Verse 17: If anyone, then, knows the good they ought to do and doesn’t do it, it is sin for them.
