For many shall come in my name, saying, I am Christ - (see Mat 24:5) - “and the time draweth nigh” (Luk 21:8); that is, the time of the kingdom in its full splendor.
and shall deceive many - “Go ye not therefore after them” (Luk 21:8). The reference here seems not to be to pretended Messiahs, deceiving those who rejected the claims of Jesus, of whom indeed there were plenty - for our Lord is addressing His own genuine disciples - but to persons pretending to be Jesus Himself, returned in glory to take possession of His kingdom. This gives peculiar force to the words, “Go ye not therefore after them.”
