The poor disciples. I would be as lost as they were on what Jesus was telling them.
They did not have ANY frame of reference, yet, for these words.
When the Spirit of truth comes, he will guide you into all the truth; for he will not speak on his own, but will speak whatever he hears, and he will declare to you the things that are to come. He will glorify me, because he will take what is mine and declare it to you. All that the Father has is mine. For this reason I said that he will take what is mine and declare it to you.
John 16:13-15 (NRSV)
