For many shall come in my name, saying, I am Christ; and shall deceive many.
For many shall come in my name, saying, I am [Christ] (see Matthew 24:5) - "and the time draweth nigh" (Luke 21:8); that is, the time of the kingdom in its full splendour.
And shall deceive many. "Go ye not therefore after them" (Luke 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 special force to the words, "Go ye not therefore after them."
