Had God revealed during Jesus' earthly ministry that He would set Israel aside and take the gospel of grace to the Gentiles?
No. During Jesus’ earthly ministry, not one word had been spoken—even by Jesus to the twelve—that God would set Israel aside, remove their temple, and turn to the Gentiles with a gospel of grace. The Gospels instead show Jesus speaking of what was promised to the nation regarding His kingship.
Les teaches that as one goes through the four Gospels, there had not been a word spoken—even by Jesus to the twelve—of a period when God would set Israel aside, take away their temple, and go to the Gentiles with a gospel of grace. Jesus was talking about everything promised to the nation regarding His being their King. The disciples had no idea He was going to be crucified. Les illustrates this by recalling a couple who asked whether Peter preached Christ crucified; he explains that Peter could not, because Christ had not yet been crucified, and they did not know He was going to be. In Luke 18:31, Jesus took the twelve and said they were going up to Jerusalem, and all things written by the prophets concerning the Son of Man would be accomplished.
