Some years ago I put up a notice in my office at work saying: PERCEPTION IS TRUTH.
A number of my staff asked me what it meant.
I explained that no matter how clever you are, how hard-working, conscientious, diligent and self-motivated. If others get the impression that you’re not really that good then, in their mind at least, that image of you is correct.
You’ll have to work really hard to convince others that you’re not really as they perceive you.
The same applies to us Christians. We may think whatever we may think about ourselves – but what image of Christianity are we portraying to others?
