Wherefore I give you to understand, that no man speaking by the Spirit of God calleth Jesus accursed: and that no man can say that Jesus is the Lord, but by the Holy Ghost.
Therefore I want you to understand that no one speaking in the Spirit of God ever says "Jesus is accursed!" and no one can say "Jesus is Lord" except in the Holy Spirit.
