Think about this, if the holy Spirit IS God and IS the Son then please explain the following;
 And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven.
If they are ONE, how can you blaspheme against the Holy Spirit and not the Father or Son?
 But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father.
If they are ONE, how can the Father know the time and the hour, but NOT the Holy Spirit or the Son?
 For the Father judgeth no man, but hath committed all judgment unto the Son:
If they are ONE, how can the Son judge WITHOUT the Father and the Holy Ghost?
Does not make sense!
