To the one who conquers, Jesus promises, "I will give him the morning star" Revelation 2:28. This promise appears with the pledge of authority over the nations for those who keep Jesus’ works to the end Revelation 2:26–28.
In Revelation 2:26–29, Jesus promises a reward to the person who “overcomes” and keeps doing what he calls “my works” all the way to the end. That person will receive authority over the nations and will share in a firm, even shattering, kind of rule. Jesus grounds this promise in what he himself has received from his Father. These verses close the message to the assembly in Thyatira within the larger set of seven messages to seven assemblies (Rev.2.18-Rev.2.29).
These verses present a promise-reward pattern at the end of the Thyatira message. The reward is explicitly tied to a defined recipient: the one who “overcomes” and who keeps doing Jesus’ “works” all the way to the end (verse 26).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Revelation 2:28, then read the surrounding section so the answer stays connected to the passage's flow.
