At last, a clear explanation! Thanks. :)
Blaspheming the Holy Spirit has always been a concern to me, since from an early age I have questioned the doctrine of the trinity. I find it difficult though, when I read passages like John 16: 7-8; 12-14 where Jesus speaks of the Holy Spirit as if it were a person. How should we answer trinitarians when they use these verses to defend their doctrinal stance?
