The antichrist

The antichrist will deny fundamental truths about Jesus Christ

2 John 7 ESV

For many deceivers have gone out into the world, those who do not confess the coming of Jesus Christ in the flesh. Such a one is the deceiver and the antichrist.

See also Mt 24:24; Mk 3:29; 1 Jn 2:22; 1 Jn 4:3

Th antichrist as a self-appointed rival to God

2 Thessalonians 2:3–4 ESV

Let no one deceive you in any way. For that day will not come, unless the rebellion comes first, and the man of lawlessness is revealed, the son of destruction, who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat 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 ESV

Children, it is the last hour, and as you have heard that antichrist is coming, so now many antichrists have come. Therefore we know that it is the last hour.

See also 2 Th 2:6–10

The final defeat of the antichrist is assured

2 Thessalonians 2:8 ESV

And then the lawless one will be revealed, whom the Lord Jesus will kill with the breath of his mouth and bring to nothing by the appearance of his coming.
