Now listen to me, you that say, "Today or tomorrow we will travel to a certain city, where we will stay a year and go into business and make a lot of money." 1
References for James 4:13
You don't even know what your life tomorrow will be! You are like a puff of smoke, which appears for a moment and then disappears.
What you should say is this: "If the Lord is willing, we will live and do this or that."
But now you are proud, and you boast; all such boasting is wrong.
So then, if we do not do the good we know we should do, we are guilty of sin.
