Mark chapter 13 is the chapter in which Jesus foretold the destruction of the temple and taught His disciples concerning the signs of the last days, the tribulation, and His second coming. When one disciple marveled at the magnificence of the temple, Jesus said that not one stone would be left upon another and that all of it would be thrown down. When Peter, James, John, and Andrew asked when that would happen and what sign there would be, Jesus first warned them not to be deceived by false christs. Wars, earthquakes, and famines would arise, but by these alone one must not conclude that the end has already come, and He said that these things are the beginnings of sorrows. The disciples might stand before councils, synagogues, and those in power because of the gospel, and might even be rejected by their families, but the gospel must first be preached to all the nations. After the great tribulation and the deception of false christs, the Son of Man will come in the clouds with great power and glory and will gather those whom He has chosen. But since no one knows that day and hour, we must not calculate dates or be shaken by the rumors of the world, but must faithfully do the work entrusted to us and always stay awake.
