I disagree, When Jesus spoke things happened. When He said be healed they were healed , when He said peace be still all was still when He said receive ye the Hole Ghost they received. To sort this out we have to do a deep dive into what happens at salvation and what is available after salvation.
You have taken one verse which contradicts everything Jesus taught and promised about the Holy Spirit coming to indwell them at Pentecost. That is not how one harmonizes scripture so it doesn't contradict itself. Otherwise you have Jesus promising them something that was not true and actually making Jesus promise false.
Does your 1 verse isolated and taken out of the biblical narrative trump the dozen below that contradict your view ?
Jesus was not Glorified until after His Ascension.
John 7:39
By this he meant the Spirit, whom those who believed in him were later to receive. Up to that time the Spirit had not been given, since
Jesus had not yet been glorified.
John 12:16
At first His disciples did not understand these things,
but after Jesus was glorified they remembered what had been done to Him, and they realized that these very things had also been written about Him.
John 13
Jesus replied, “You do not realize now what I am doing,
but later you will understand…. I am telling you now before it happens, so that when it does happen you will believe that I am who I am.”
Jesus promised the disciples He would bring to their remembrance
when Pentecost came and the Holy Spirit would be in them and guide them into all truth.
John 14:26
But the Comforter,
which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you
John 16:7
"It is expedient for you that I go away; for if I go not away the Comforter will not come unto you;
but if I depart I will send him unto you."
Jesus had not yet departed in John 20:22 had He ? He was still with them.
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.
The Promise of the Spirit at Pentecost !
Luke 24:49
And, behold, I send the promise of my Father upon you:
but tarry ye in the city of Jerusalem, until ye be endued with power from on high.
Acts 1:4,5
And, being assembled together with
them, commanded them that they should not depart from Jerusalem,
but wait for the promise of the Father, which,
saith he, ye have heard of me…
hope this helps !!!
