1 John 2:18-22

18My children, the world will soon end. You have heard that the enemy of Christ will appear. You can see that many enemies of Christ have already appeared. This shows us that the world will end soon.

19These people used to be in our group of believers. But they left us. They never really belonged to our group. If they had been true believers, they would have remained with us. When they left us, it showed clearly that none of them really belonged to us.

20But Christ, the Holy One, has given you the Holy Spirit. As a result, you all know what is true.

21That is why I am writing to you. It is not because you do not yet know God's true message. I am writing to you because you do know that true message. And you can be sure that there are no lies in it.

22Who is the one who tells the worst lies? It is anyone who says that Jesus is not the Messiah. A person like that is the enemy of Christ. He is speaking against God, the Father, and against Jesus, his Son.
