The ocean is so deep that it is beyond our minds to grasp how massive and complex nature is in this world. As much as we think we have discovered the world, we're not even close to halfway through discovering what's going on in the world, even in the water. All the animals, all the birds, all the bugs, all the fish.
And why did Hashem create this whole beautiful world? Why did Hashem create such a beautiful stage, such a beautiful setting? For what? For a person to spend time on his iPhone? For a person to fight with other people? For a person to run after money his whole life? That's why Hashem created such a beautiful world? No way, no way. There has to be a greater purpose.
If Hashem made such a beautiful world, that means the people He created to use the world are beautiful. They have high neshamot (souls). Hashem has high expectations of us. What are those expectations? To overcome bad. Work on our middot (character traits), work on being good people, be Baalei chesed (people of kindness), learn Torah, do more mitzvot (commandments), say no to sins, and say no to the Yetzer Hara (evil inclination). Hashem has high expectations of what we're supposed to perform in this world. And that is to become great people.
