You are a convex lens.

OK, I will admit that I actually had to look that up. A convex lens is one that makes objects look larger, like a magnifying glass. Paul lived his whole life as a convex lens. He wanted people to look at him in any situation--good, bad, or ugly--and see Jesus Christ looming large. People at looking at you too. And they're looking through you at Christ. Is He bigger or smaller with you as the lens?
