A believer is spiritually united with Christ. As Christ died, the believer has died to the elemntal spirits of the world. This is a metaphor for no longer responding to the elemenatry spirits of the world. The believer is no longer controlled by them. (See: [[rc://en/ta/man/jit/figs-metaphor]])
Possible meanings are 1) spiritual powers that some people thought control what happens on earth, or 2) the laws or moral principles of the world. See how you translated this in [Colossians 2:8](../02/08.md).
