James 5:9

You are to be patient for the coming of the Lord. What may happen as you get impatient is that you may begin to complain or grumble against one another. It can certainly happen because there are a number of different people and they can be annoying at times. Being patient for the coming of the Lord does not include grumbling against one another. Rather, you should just be patient. Complaining about others means your attention is focused on them and not on the coming of the Lord. Therefore, don't worry about them and simply focus on the Lord, waiting for his return.
