I John 4:1-3, 7, 15

Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world. By this you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world.

Beloved, let us love one another, for love is of God; and everyone who loves is born of God and knows God.

Whoever confesses that Jesus is the Son of God, God abides in him, and he in God.
