Others stressed the Son of Man, a distinctly other-worldly figure who would appear as a judge at the end of time; and some harmonised the two by expecting a this-worldly messianic kingdom which would last for a set period and be followed by the other-worldly age or World to Come. Some thought the Messiah was already present, but unrecognised due to Israel's sins; some thought that the Messiah would be announced by a fore-runner, probably Elijah (as promised by the prophet Malachi, whose book now ends the Old Testament and precedes Mark's account of John the Baptist). None predicted a Messiah who suffers and dies for the sins of all the people. The story of Jesus' death therefore involved a profound shift in meaning from the tradition of the Old Testament.
