Luke's Gospel made the subject of Judgment clear.
Luke 17: 25-37...
- But first must he suffer many things, and be rejected of this generation.
- And as it was in the days of Noe, so shall it be also in the days of the Son of man. They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.
- Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded; But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
- Even thus shall it be in the day when the Son of man is revealed. In that day, he which shall be upon the housetop, and his stuff in the house, let him not come down to take it away: and he that is in the field, let him likewise not return back.
- Remember Lot's wife.
- Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it.
- I tell you, in that night there shall be two men in one bed; the one shall be taken, and the other shall be left. Two women shall be grinding together; the one shall be taken, and the other left. Two men shall be in the field; the one shall be taken, and the other left.
- And they answered and said unto him, Where, Lord? And he said unto them, Wheresoever the body is, thither will the eagles be gathered together.
The picture of Christ as a Divine Judge is the prelude to establishing the Promised Kingdom on Earth. The Kingdom postponed in Christ's day - will thus take effect at the Divine Judgment of Christ (at the end of the seven year Tribulation). After Judgment - all humanity at that time will accept Christ as Messiah and be sanctified. The Promised Kingdom will be established for the first time - since it's postponement during the earthly ministry of Christ. As Jesus prayed in the Lord's prayer - Thy will be done on Earth - as it is in Heaven.
Matthew 25 mentions of the Son of man, the Bridegroom, the King, and the Judge. In Luke 17 - Christ the Judge is prevalent.
