I know that this thread is about does the bible really teach that Jesus IS God (not was, because Jesus DID rise from the dead and IS very much alive and without the resurrection we would have no hope), but the subject of the Holy Spirit has been brought up so I must interject here and say that the Holy Spirit like the Father (who is also Spirit) and Jesus (the Son or same as God) is also God and not just some force or something. The bible clearly states that God is One, but the bible also makes clear that God is three "persons".
