1 John 2:18

“For many will come in My name, saying, ‘I am the Christ,’ and will deceive many.

And do this, knowing the time, that it is already the hour for you to awaken from sleep; for now salvation is nearer to us than when we believed.

The night is almost gone, and the day is at hand. Therefore let us lay aside the deeds of darkness and put on the armor of light.

The end of all things is at hand; therefore, be of sound thinking and sober spirit for the purpose of prayer.

Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son.

Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.

and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world.

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