A gas engine uses the spark from the spark plug to cause the fuel air mixture to explode.
In a gas engine if the spark plug is not working that cylinder will not fire.
In a diesel engine the glow plugs are just devices that are used to pre-heat the fuel-air mixture to make the mixture 'explode' with less compression. They are used only to start the engine, and on modern diesel engines, often continue to glow and warm the mixture for a period of time after the engine is started to aide the combustion process for a cold engine. I believe on the 6.7L that is 20 minutes.
The above poster was 100% correct. With one bum glow plug your engine should run fine and you may not even notice it aside from the CEL.
There are a lot of people on here more knowledgeable about diesel engines than myself that can provide more detail and info but this is my nickel summary.

It is nothing like a spark plug. A diesel uses compression ignition. The fuel/air mixture is literally squeezed until it explodes.
A gas engine uses the spark from the spark plug to cause the fuel air mixture to explode.
In a gas engine if the spark plug is not working that cylinder will not fire.
In a diesel engine the glow plugs are just devices that are used to pre-heat the fuel-air mixture to make the mixture 'explode' with less compression. They are used only to start the engine, and on modern diesel engines, often continue to glow and warm the mixture for a period of time after the engine is started to aide the combustion process for a cold engine.
