Traditionally, Christianity has defined sin in a way that made it easy to blame structural problems on individual people; in the process of doing so, it has emphasized the redeemed individual over the redeemed world.
This reaches its height in the view that you can replace “the world” in John 3:16 with your own name, as seen in this devotional on becoming a Christian among other places.
But John 3:16 doesn’t actually allow for this. The Greek word generally translated as “the world” is kosmos, and it means more or less the same thing that the word cosmos means in English.
John 3:16 doesn’t say that you, individually, are what God loves (which isn’t to say that he doesn’t). It says that God’s love is for the entirety of creation. Changing it to refer to an individual person inverts the verse, changes it from a message on the brokenness and ultimate redemption of creation to a message on the sinfulness and hopeful redemption of the individual; it changes from a Christ who saves the world to a Christ who encourages us to abandon the world in favor of salvation.
