The Rejection of the wholly truth aka holy spirit aka the whole truth and nuting but the truth, is akin to blaspheming of the holy spirit.
What it simply means is rejecting the truth which is manifested in doing going. In our example casting out repugnant ideas, concepts, beliefs structutures, unforgiveness, fornication, lies...these are all demonic behaviors which kills, destroy and steal a person or peoples lives.
When a person or group reject these, they are on their way to confusion of faces, war, conflicts, hurt, sickness, pain, suffering...and many other things that cuts off from finding any type o life.
