There is only one passage in the Bible where it is stated specifically that The Holy Spirit is God. In
Acts 5:1-4 we find Ananias and Sapphira, a husband and wife, lied to
"the Holy Spirit" (verse 3) then in verse 4 the scriptures say they
"lied to God." So who was lied to, God or the Holy Spirit? Both, because
the Holy Spirit is God.
There are many many more that "say" the same thing in other ways. For instance, the scriptures state that Jesus is "the Son of God" no less than 50 times, so quite simply Jesus is God's son.
Luke 1:35, "And the angel answered and said unto her, The
Holy Spirit shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called
the Son of God." Based on this passage
Jesus is the son of the Holy Spirit, so the Holy Spirit
must be God. There are many many more passages that could be quoted but you get the idea, besides I'm beginning to believe the mods have it in for me, so I will shut up. :-)
