1 Corinthians 12:2-3

You know that when you were pagans, you were led off after speechless idols; however you were led off [whether by impulse or habit]. Therefore I want you to know that no one speaking by the [power and influence of the] Spirit of God can say, “Jesus be cursed,” and no one can say, “Jesus is [my] Lord,” except by [the power and influence of] the Holy Spirit.
