Here’s a quote to chew on regarding the ethics of labor.
… we can [...] be quite sure that a great many of our economic ills arise from our failure to recognize the sanctity of six days of labour. Â Labour is not only a duty; it is a blessing. Â And, in like manner, six days of labour are both a duty and a blessing. Â If this principle were firmly established in our thinking, then the complications and hypocrisies often associated with the demand for a five-day week would not have so readily afflicted our economy, and moral degeneration would not have proceeded at the pace we have witnessed.
John Murray. Â Principles of Conduct (Grand Rapids: Eerdmans, 1957), 83.
I appeal to you, brothers, to watch out for those who cause divisions and create obstacles contrary to the doctrine that you have been taught; avoid them. For such persons do not serve our Lord Christ, but their own appetites, and by smooth talk and flattery they deceive the hearts of the naïve. (Romans 16:17-18)
