After a person contemplates the notion that “the world was created for me,” he reaches the conclusion that he must do something.
It does not matter what others will do, nor whether they are good or evil, nor. whether they are present or absent, because in this regard the entire world is merely the backdrop, merely the environment in which he exists.
The same applies to his relationship with God, regarding which he must think: Everyone else in the world is a helper, an attendant, but only I am God’s servant in the world.
God created the world for me.
I am its center and its reason for being, and therefore its existence depends on me.
The existence of the entire kingdom hinges on me accepting the yoke of the kingdom, serving Him and doing His will.
Rabbi Adin Steinsaltz
