“One of the most interesting and harmful delusions to which men and nations can be subjected is that of imagining that there is some sort of ground rule applied to the universe by which final triumph if you are strong enough, and the ultimate success of virtue if you are good enough, is inevitable.”

Simplified Meaning:

People often believe that if you are strong or virtuous, you will definitely succeed in the end. However, this isn't always true. History shows us many examples where good and strong people did not necessarily achieve what they aimed for. For instance, there have been great leaders who fought bravely but still lost wars and heroes who stood against injustice yet faced great suffering. Imagine a student who always studies hard and is kind to everyone. They might believe that their good actions and efforts will guarantee straight A’s and popularity. But life doesn't always work out that way. Even with all their hard work, there might be times when they struggle with subjects or face misunderstandings with friends. The main lesson is to understand that strength and goodness increase your chances of success, but they do not promise it. Life is unpredictable and influenced by various factors beyond one's control. Rather than expecting inevitable success, it’s wiser to stay strong and good simply because it’s the right thing to do, and to be resilient when things don't go as planned.
