Acts 19:2 (NLT2) “Did you receive the Holy Spirit when you believed?” he asked them. “No,” they replied, “we haven’t even heard that there is a Holy Spirit.”
Every time we say, "I believe in the Holy Spirit," we mean that we believe that there is a living God able and willing to enter human personality and change it. --J. B. Phillips (1906-1982)
