1 John 4:1-2

1My friends, do not believe everyone who says that they speak God's message. There are many false prophets who are travelling around everywhere. They say that they have a message from God's Spirit, but the message comes from a false spirit. So check each message carefully to see if it is really from God.

2How do you know whether a person has God's Spirit in him? He must agree that Jesus is God's Messiah who was born as a human baby. If someone says that, then he has God's Spirit.
