Yes, Jesus speaks of the Father....the Comforter had not yet been given. His work is "behind the scenes" at this time.
He spends a great deal of time on the Holy Spirit, we see him alluding to his work in the yellow above.
As Jesus explained when speaking of the Holy Spirit....He will "testify of me". His work is ongoing. Our Lord Jesus Christ is the one who is to receive all the glory, and the Godhead is in agreement on this.
John 16:13 Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear, that shall he speak: and he will shew you things to come.
John 16:8-11 And when he is come, he will reprove the world of sin, and of righteousness, and of judgment Of sin, because they believe not on me; Of righteousness, because I go to my Father, and ye see me no more; Of judgment, because the prince of this world is judged.
So rather than moving on from the verses I offered, believe them and build on them. Why not see what is set before you instead of rushing off for further proof? The
basics are there in our Lord's words, and Paul, himself builds on that foundation.
1 Corinthians 3:11 For other foundation can no man lay than that is laid, which is Jesus Christ.
