Antichrist, the

One who is directly and implacably opposed to Jesus Christ.

The antichrist will deny fundamental truths about Jesus Christ

2 John 1:7 See also Matthew 24:24 parallel Mark 13:22; Mark 3:29; 1 John 2:22, 1 John 4:3

For many deceivers have gone out into the world, refusing to confess the coming of Jesus Christ in the flesh. Any such person is the deceiver and the antichrist.

Th antichrist as a self-appointed rival to God

2 Thessalonians 2:3–4 See also Daniel 7:7–8, Daniel 7:24–25, Daniel 8:9–12, Daniel 8:23–25, Daniel 11:36–45; Revelation 13:1–10, Revelation 13:11–18

Let no one deceive you in any way, for it will not come until the rebellion occurs and the man of lawlessness — the son of destruction — is revealed. He will oppose and exalt himself above every so-called god or object of worship. So he will seat himself in the temple of God, proclaiming himself to be God.

The coming of the antichrist is a sign of the ``last days''

1 John 2:18 See also 2 Thessalonians 2:6–10

Children, it is the last hour; and just as you have heard that the antichrist is coming, so now many antichrists have appeared. This is how we know it is the last hour.

The final defeat of the antichrist is assured

2 Thessalonians 2:8 See also Daniel 7:26–27, Daniel 8:25, Daniel 11:45; Revelation 17:7–14

And then the lawless one will be revealed, whom the Lord Jesus will slay with the breath of His mouth and annihilate by the majesty of His arrival.
