14 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.
15 What you should say is this: “If the Lord is willing, we will live and do this or that.”
16 But now you are proud, and you boast; all such boasting is wrong.
17 So then, those who do not do the good they know they should do are guilty of sin.
