1 Corinthians 12:2-4 (New International Version)

²You know that when you were pagans, somehow or other you were influenced and led astray to mute idols. ³Therefore I tell you that no one who is speaking by the Spirit of God says, "Jesus be cursed," and no one can say, "Jesus is Lord," except by the Holy Spirit.

 ⁴There are different kinds of gifts, but the same Spirit.
