This is how you can recognize the Spirit of God: every spirit that acknowledges that Jesus Christ has come in the flesh is from God, and every spirit that does not acknowledge Jesus is not from God. This is the spirit of the Antichrist, about whose coming you have been told, and that it is already in the world.
In love there is no fear; indeed, perfect love casts out fear, because fear has to do with punishment, and whoever fears has not yet achieved perfection in love.
If someone says, “I love God,” but at the same time hates his brother, he is a liar. For whoever does not love the brother whom he has seen cannot love God whom he has not seen.
