What does Revelation 2:17 mean?

If you have ears, listen to what the Spirit is saying to the communities. To the one who wins the victory, I’ll give some of the hidden manna. I’ll also give them a white stone with a new name written on it, known only to the one who receives it. Revelation 2:17 - Modern Text Bible

(He promises spiritual nourishment and a unique, personal identity to those who stay faithful.)
