Have you ever used a magnifying glass? What is the purpose of a magnifying glass?
A magnifying glass does several things: it makes the object look bigger thus making it easier to examine and see. It also brings the object into greater focus, enabling us to see detail we would not be able to see without the magnification the glass is performing.
The word Paul uses here, which is translated magnify or exalted, is the word ‘megaluno’. It comes from the word ‘mega’: which means great, strong. To make great, enlarge.
The Idea is that our bodies, our actions in these bodies, act like magnifying glasses. People look through our actions to see Jesus.
In other words, through our words, actions and gestures, people are to be able to look at you and see Jesus enlarged.
They are to be able to see Jesus easier through your actions.
