Antichrist

An Antichrist is a figure who opposes God.  The word is used to describe a spirit of rebellion against God, "...the spirit of the Antichrist..." (1 John 4:3) and of a specific future person identified as the man of lawlessness (2 Thess. 2:3).  He actively opposes Christ (2 Thess. 2:4) and when he arrives, he will be able to perform miracles (2 Thess. 2:9).  Some believe he will be an incarnation of Satan and as such will be able to deceive many.  His number is 666 (Rev. 13:18).  A further possible description of him might be found in Zech. 11:15-17.
