Mark 13:23 Meaning

21And then if any man shall say to you, Lo, here is Christ; or, lo, he is there; believe him not:

22For false Christs and false prophets shall rise, and shall shew signs and wonders, to seduce, if it were possible, even the elect.

23But take ye heed: behold, I have foretold you all things.

24But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,

25And the stars of heaven shall fall, and the powers that are in heaven shall be shaken.
