This brief version by Mark of the so-called Olivet discourse finds its more lengthy parallel passage in Matthew 24, 25; also Luke 21. It references the Tribulation and the Second Coming of Jesus Christ at the end of the Tribulation. These passages are often confused with the Rapture of the Church. They do not pertain to the Rapture. That glorious event (Titus 2:13) will have already taken place some time before the Tribulation. Read this short chapter with that in mind.
