Matthew 12:28-32

28But if I cast out devils by the Spirit of God, then the kingdom of God is come unto you. 29Or else how can one enter into a strong man’s house, and spoil his goods, except he first bind the strong man? and then he will spoil his house. 30He that is not with me is against me; and he that gathereth not with me scattereth abroad.

31Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men. 32And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come.
