Warning against Judging Others
Don’t speak evil against each other, dear brothers and sisters. If you criticize and judge each other, then you are criticizing and judging God’s law. But your job is to obey the law, not to judge whether it applies to you. God alone, who gave the law, is the Judge. He alone has the power to save or to destroy. So what right do you have to judge your neighbor?
Warning about Self-Confidence
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 all such boasting is evil.
Remember, it is sin to know what you ought to do and then not do it.
