'Anti christ' in the Bible

Then the lawless one [the Antichrist] will be revealed and the Lord Jesus will slay him with the breath of His mouth and bring him to an end by the appearance of His coming.

The coming of the [Antichrist, the lawless] one is through the activity of Satan, [attended] with great power [all kinds of counterfeit miracles] and [deceptive] signs and false wonders [all of them lies],

Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time.

Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.

And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.

Little children (believers, dear ones), you are of God and you belong to Him and have [already] overcome them [the agents of the antichrist]; because He who is in you is greater than he (Satan) who is in the world [of sinful mankind].

For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.
