"ADVERSITY Develops Internal BELIEF" means that when we face tough times and problems, it can make our personal beliefs and confidence inside us stronger. Like when we go through hard things, we have to use our own ideas and what we think is right to get through. 

This can help us understand ourselves better, feel more sure about who we are, and become better at handling tough situations. 

So, when we deal with difficulties, it's like a way of growing our inner beliefs and feeling more confident about facing challenges in the future."
