Mark 13:21 Meaning and Commentary

Mark 13:21

And then if any man shall say to you
During those days of tribulation and affliction, or when shortened and at an end:

lo! [here is] Christ, or lo! [he is] there;
the Messiah has appeared in such or in such a place, to deliver you from your national distresses and calamities, and from the Roman yoke and bondage:

believe him not;
give no credit to such a report, for the reason following; (See Gill on Matthew 24:23).

Mark 13:21 In-Context

19 "These are going to be hard days - nothing like it from the time God made the world right up to the present. And there'll be nothing like it again.
20 If he let the days of trouble run their course, nobody would make it. But because of God's chosen people, those he personally chose, he has already intervened.
21 "If anyone tries to flag you down, calling out, 'Here's the Messiah!' or points, 'There he is!' don't fall for it.
22 Fake Messiahs and lying preachers are going to pop up everywhere. Their impressive credentials and dazzling performances will pull the wool over the eyes of even those who ought to know better.
23 So watch out. I've given you fair warning.
