This is a very inflammatory move on the part of the PA. In essence, they are already claiming that Jerusalem, the city of Christ the King, is the property of the Palestinians. David won that city as a part of his conquest of the promised land. By taking control, his line became the heirs of the kingship/priesthood of Melchizedek. The Messiah Jesus, by right of succession, will return to Jerusalem as the King/Priest after the order of Melchizedek. "For he testifieth, Thou art a priest for ever after the order of Melchisedec." Hebrews 7:17
Jerusalem was only temporarily abandoned by the Jews due to their turn from God in God's redemptive effort to refocus them on His love and salvation. The fact that this city now is in Jewish control and the fact that it is terribly contested by the very people prophesied to claim it as theirs with a terribly false claim shows us that Jesus is near to returning! It is a pathetic attempt by a loser really. Satan knows that if the sons of Abraham, Isaac and Jacob keep the land he is nearer to that appointment with the abyss that he has. Sorry devil!! You can't beat the King of Kings and Lord of Lords! Your day to bow at His knees before all humanity and proclaim that He truly is Lord is quickly approaching!
