Do you ever feel like a complete poser knowing that you need weekly drug injections to keep your muscles?
No more than someone who needs food to keep their muscles. Our body doesn’t produce nutrients naturally. If someone consumes a protein supplement are they a poser?
Using your line of thinking we should just forego any modern conveniences or substances that make our life better or easier. Better turn off that air-conditioning and suffer in the heat. That nice cool air isn’t natural. If God wanted you to be comfortable he would have created you with built-in air conditioning. Don’t drive anywhere either. Better to just walk than have to rely on a car that you didn’t build.
