“Look here, you who say,’Today or tomorrow we are going to a certain town and will stay there a year. We will do business there and make a profit.’ How do you know what your life will be like tomorrow? Your life is like the morning fog- it’s here a little while, then it’s gone. What you ought to say is, ‘If the Lord wants us to, we will live and do this or that.’ Otherwise you are boasting about your own plans, and such boasting is evil.
Remember, its a sin to know what you ought to do and then not do it.” (James 3: vv. 13-17, NLT)
