Dear Jim,
I was looking up these scriptures in the NIV and NAV.. They seem to give some insite as to what was different about the holy spirit that Jesus sent down and the prior.
John 15:26 NAV "When the Advocate comes whom I will send you from the Father, the Spirit of truth that proceeds from the Father, he will testify to me. And you also testify, because you have been with me from the beginning."
John 15:26 NIV "When the Counselor comes whom I will send to you from the Father, the Spirit of truth who goes out from the Father, he will testify about me. And you also must testify, for you have been with me from the beginning."
Jim, the NIV seems more accurate here, when it says the spirit of God will testify about Jesus.. Maybe Jesus had input as to what was sent..
John 16:7 NIV "But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you. When he comes, he will convict the world of guilt in regard to sin and righteousness and judgement:"
John 16:7 NAV "But I tell you the truth, it is better for you that I go. For if I do not go, the Advocate will not come to you. But if I go, I will send him to you.........."
Jim, this is the one about, the spirit not being able to come unless Jesus dies and sends him to the apostles.
John 16:12 NAV "I have much more to tell you, but you cannot bear it now. But when he comes, the Spirit of truth, he will guide you to all truth. He will not speak on his own, but he will speak what he hears, and will declare to you the things that are coming. He will glorify me, because he will take from what is mine and declare it to you. Everything that the Father has is mine; for this reason I told you that he will take from what is mine and declare it to you."
John 16:13 NIV is the same here.
So, Jim, So it appears that the spirit is God's spirit, not a person, that speaks on his own. It also seems to say, the spirit can teach is a more effective way, than Jesus speaking to them verbally. The spirit seems to be God's spirit which was given to Jesus..to do with what I wants with.. What do you think of these scriptures????
