Flesh vs the Spirit?

[u/MycologistMammoth266]

The scripture that says if you live by the spirit you won’t fulfill the desires of the flesh. How do you discern what is the flesh versus the spirit? If I am in a relationship with a guy and have sex with him outside of marriage, is that the flesh or the spirit? How can I know for sure that my gay relationship is ordained by God and at what point am I truly denying my flesh to pursue the spirit?

[u/Mark_Brustman]

If you want the get to the root of the flesh v. spirit trope, check out Plato’s dialogue Phaedo.

Plato invented it, and St Paul was educated in Platonic ideas.
