When you have a sense of calling, whether it’s to be a musician, soloist, artist, in one of the technical fields, or a plumber, there is something deep and enriching when you realize it isn’t just a casual choice, it’s a divine calling. It’s not limited to vocational Christian service by any means.
Technology is nothing. What’s important is that you have a faith in people, that they’re basically good and smart, and if you give them tools, they’ll do wonderful things with them.
Plumbing originated during ancient civilizations such as the Greek, Roman, Persian, Indian, and Chinese cities as they developed public baths and needed to provide potable water and wastewater removal, for larger numbers of people.
