The bible says lack of knowledge my people perish,if u do not have know God's word that is where the devil put his ideas into your mind that is were u say things in negative way .

The holy spirit is unseen creature and something which u have never seen how can u say something about it.Jesus said any one who speak against the HOly spirit shall not be forgiven neither in his present age or years ahead of him.He himself is holy and everything within him is holy.

It was too early for the name of Jesus to known ,he was sent to the world to fullfil what he was sent to do.he was also sent to world to let the name of father be known in the world.

I think that was not the main reason he's name must be known ,miracle is for us,but taken our sins upon his self and been cruisify on the cross is to make his name be known to the world.
