In general, we know about God the Father. And we certainly know about God the Son, Jesus Christ. But what about the third member of the Godhead, God the Holy Spirit? Do we know him as we ought? Do we understand His identity, personality and work?

The answer for too many of us is: not really. In this five-part series we’ll take an in-depth look at the Biblical doctrine of the Holy Spirit. More than this, we’ll seek ti understand what it means to be fully filled with the Spirit. Our goal will be to know Him and to be known Him. He is, after all, for far too many of us, the Unknown God.
