No Complaining.

The apostle exhorts them in these verses to adorn their Christian profession by a suitable temper and behaviour. By a cheerful obedience to the commands of God: "Do all things, do your duty in every branch of it, without murmurings. Do it, and do not find fault with it. Mind your work, and do not quarrel with it." God's commands were given to be obeyed, not to be disputed. This greatly adorns our profession, and shows we serve a good Master, whose service is freedom and whose work is its own reward.

By peaceableness and love one to another. "Do all things without disputing, wrangling, and debating one another because the light of truth and the life of religion are often lost in the heats and mists of disputation. - Matthew Henry
