Mark 1:15

And saying, the time is fulfilled,.... Either that which was fixed for the end of the law and prophets, the legal and Mosaic dispensation, and the Jewish church state; or the fulness of time for the Messiah's appearance in the world; which was agreed upon between the Father and the Son, was predicted in various prophecies, and the people of the Jews were in a general expectation of:
