Most of us - even if we don't fully understand it - will agree that we believe in God the Father and God the Son. But when it comes to the Holy Spirit, we often treat him as "a member of the Trinity once removed" or like the crazy uncle of Jesus. In Part 2 of "The Helper," Paul explains that the Holy Spirit is so much more than we expect. He's God, yes, but he's also one who wants to be our friend.
