What does it mean to not love the world according to the Bible?

In 1 John 2:15-17, John admonishes believers not to love the world or the things in it, emphasizing that the love of the Father cannot coexist with love for worldly things. The 'world' refers to a system of values influenced by sin, characterized by the lust of the flesh, the lust of the eyes, and the pride of life. Such desires are temporary and lead to spiritual death. Believers are instead called to do the will of God, which leads to eternal life. By focusing on Christ, Christians secure their identities and values in the eternal rather than the fleeting nature of the worldly system.
