If the Lord wills

James 4:13 - 15 says, "Go to now, ye that say, today or tomorrow we will go into such a city, and continue there a year and buy and sell, and get gain: whereas ye know not what shall be on the morrow. For what is your life? It is even a vapor, that appeareath for a little time, and then vanisheth away. For that ye ought to say, if the Lord will, we shall live, and do this, or that." Where are you going tomorrow? I'm going fishing, that is, if the Lord wills.
