To Smyrna, Jesus says, "Be faithful unto death, and I will give you the crown of life" Revelation 2:10. The statement is tied to coming suffering and testing described in the same verse Revelation 2:10.
In Revelation 2:8–11, Jesus addresses the assembly in Smyrna with words meant to steady them for suffering. He acknowledges their pressure and lack of resources, yet calls them “rich” in a deeper sense. He also names hostile speech from a group claiming Jewish identity. This message is the second of seven short, targeted messages to assemblies in Asia Minor (Revelation 2–3), each beginning with an instruction to write to an “angel” connected to that assembly and ending with a call to listen and a promise to “the one who overcomes.” The speaker introduces himself using a title that.
Revelation 2:8–11 presents Jesus as the authoritative speaker to Smyrna (“the first and the last”) and as one who truly passed through death and now lives (Rev 2:8). That self-description sets the frame: their suffering is real, but death is not the final boundary.
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 2:10, then read the surrounding section so the answer stays connected to the passage's flow.
10Don`t be afraid of the things which you are about to suffer. Behold, the devil is about to throw some of you into prison, that you may be tested; and you will have oppression for ten days. Be faithful to death, and I will give you the crown of life.
