Matthew 24:23

Then. After the “great tribulation” of vs. 21, 22. The warning of vs. 23-28 applies specifically to the last days of earth’s history, and was “given as a sign of the second advent” (DA 631). A similar warning had already been given in vs. 4, 5, but there it was set forth primarily “as one of the signs of Jerusalem’s destruction” (DA 631) and was fulfilled before the fall of that city in A.D. 70. But the same warning, repeated in vs. 23-28, was given for “those who live in this age of the world,” for “now, in unmistakable language, our Lord speaks of His second coming, and He gives warning of dangers to precede His advent to the world” (DA 628, 631).

You. Jesus addresses the disciples concerning events at the close of time as representatives of believers alive at the end of time.

Christ. The Greek equivalent of the Heb. Mashiach, “Messiah” (see on ch. 1:1).

Believe it not. See on vs. 4, 5.
