The Second Coming is the long awaited return of Christ to the earth by the Jews. They missed him the first time when he was born into the world and failed to recognise him as their saviour. This time when He returns it will be in no way miss interpreted, He will come for all to see on a white horse with His army following. No one will be in doubt as to who he is especially the Jew.
This Second Coming is not to be mixed up with the Rapture, where Christ does come but not to the earth. The Second Coming refers to His actual presence n earth, the first being His birth and life on earth some 2000 years ago. This final Coming is specifically for the Jew and the final stage of God's plan. The Second Coming heralds in a new age, the age of the millennial reign of Christ. But before this starts Christ will judge the living nations who are on the earth at His coming. Only those who are found worthy, those who have not took the mark of the beast will enter the millennial reign. Those that sided with the Devil will be cast into the lake of fire ready for the final Judgemnet.
