When the Lord had finished all that related to Jerusalem, He came in the rest to His own coming, and gives them signs thereof, useful not for them only, but for us and for all who shall be after us.
As above, the Evangelist said, “In those days came John the Baptist,” [Matt 3:1] not implying immediately after what had gone before, but thirty years after; so here, when He says, “Then,” He passes over the whole interval of time between the taking of Jerusalem and the beginnings of the consummation of the world.
Among the signs which He gives of His second coming He certifies them concerning the place, and the deceivers. For it shall not be then as at His former coming, when He appeared in Bethlehem, in a corner of the world, unknown of any; but He shall come openly so as not to need any to announce His approach.
Wherefore, “If any man shall say unto you, Lo, here is Christ, or there, believe not.”
