Well, I’ve got a job that requires 24/7/365 attention. Without what I do, modern society crumbles. Prior to that, at one point, I was a US Army Infantryman.
Both of those things cause me to “not keep the sabbath”. My soul is not in doubt because of this.
Some jobs are necessary. God knows this. You can still give thanks to God on the Sabbath and still do your job.
