1 Corinthians 12:
1 Now concerning spiritual gifts, brethren, I would not have you ignorant.
2 Ye know that ye were Gentiles, carried away unto these dumb idols, even as ye were led.
3 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.
1 Cor.12:1-3
