John 16:13 But when he, the Spirit of truth, comes, he will guide you into all the truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. 14He will glorify me because it is from me that he will receive what he will make known to you. 15All that belongs to the Father is mine. That is why I said the Spirit will receive from me what he will make known to you.”
We all need an advocate. Because eventually we always come to the end of ourselves and find we are still lacking.
