Is a spirit against God
Anyone who denies that Christ is come in the flesh is an Antichrist. We usually hear about the “great one” – 666 (Six hundred and sixty six)- but there are many Antichrists.
The number 666 is also mentioned in King Solomon on the amount of gold he required as tribute.
Remember that there will be two versions of the returning Christ. The first, which will appear to be the Christ (carrying a bow), then the real Christ, with a sword.
