Which periodical focused on the second coming of Christ and was produced by Himes?

The periodical that focused on the second coming of Christ and was produced by Himes is "The Signs of the Times." This publication, established in the mid-19th century, was significant in promoting the Adventist message, particularly emphasizing the imminent return of Jesus Christ. Himes, a prominent figure in the early Adventist movement, played a crucial role in disseminating the beliefs associated with the second coming through this periodical.

While other publications like "Advent Review" and "Herald of Truth" were important in the Adventist tradition, they either came later or had broader focuses that included various aspects of Christian life and doctrine, rather than specializing exclusively on the second coming. "Watchman," similarly, did not have the same direct emphasis or historical connection to Himes and the early Adventist movement concerning eschatological teachings. Thus, "The Signs of the Times" stands out as the correct answer, encapsulating the central themes Himes advocated during a critical time of Adventist history.
