1 John 4:2-3 CSB [2] This is how you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh  is from God,  [3] but every spirit that does not confess Jesus  is not from God. This is the spirit of the antichrist,  which you have heard is coming; even now it is already in the world. https://bible.com/bible/1713/1jn.4.2-3.CSB
