The apostles were not serene, confident mystics awaiting resurrection.
They were never serene, confident mystics of any kind, before or after the death, burial and resurrection.
They were shattered human beings, and the New Testament is remarkably honest about it.
The fact that Jesus had to die was hidden from them. What does that have to do with anything?
Luke 18:31-34 (AKJV/PCE)
(18:31) ¶ Then he took [unto him] the twelve, and said unto them, Behold, we go up to Jerusalem, and all things that are written by the prophets concerning the Son of man shall be accomplished. (18:32) For he shall be delivered unto the Gentiles, and shall be mocked, and spitefully entreated, and spitted on: (18:33) And they shall scourge [him], and put him to death: and the third day he shall rise again. (18:34) And they understood none of these things: and this saying was hid from them, neither knew they the things which were spoken.
When Jesus told Peter about it, Peter tried to stop Him.
Matt 16:21-23 (AKJV/PCE)
(16:21) ¶ From that time forth began Jesus to shew unto his disciples, how that he must go unto Jerusalem, and suffer many things of the elders and chief priests and scribes, and be killed, and be raised again the third day. (16:22) Then Peter took him, and began to rebuke him, saying, Be it far from thee, Lord: this shall not be unto thee. (16:23) But he turned, and said unto Peter, Get thee behind me, Satan: thou art an offence unto me: for thou savourest not the things that be of God, but those that be of men.
Pentecost, in this light, is a reconstitution of a broken community. Taken together, the evidence is overwhelming:
Overwhelming of WHAT? Their grief?
That they were saddened by the death of Jesus... no kidding... call the news.
This is a point that we Pauline Mid-Acts dispensationalists often make. They, even at and after Pentecost, they were NOT preaching the cross as GOOD NEWS. That began with PAUL! Peter was INDICTING the nation of Israel for MURDERING their Messiah.
Acts 2:23 (AKJV/PCE)
(2:23) Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain:
That is NOT Peter declaring GOOD NEWS to the people of Israel (the a few proselytes).
Peter says, "I am going fishing," and the others follow (John 21:3).
Peter was a fisherman. What is the POINT? That God "departed from the world" when Jesus died? That did not happen.
This is resignation, a return to the life they had before Jesus called them. Mary Magdalene weeps at the tomb (John 20:11–13). Her grief is raw and unfiltered. There is no sense of triumph or expectation, only loss. On the road to Emmaus, two disciples confess: "We had hoped that he was the one to redeem Israel" (Luke 24:17–21). Their hope is explicitly described as lost. They are bewildered, grieving, and disoriented.
Again, what is you POINT? Of course they were sad and dejected. Their Messiah was dead and they did not know about the reason why.
John 20:9 (AKJV/PCE)
(20:9) For as yet they knew not the scripture, that he must rise again from the dead.
The Holy Spirit certainly descended:
“When the day of Pentecost arrived, they were all together in one place. And suddenly there came from heaven a sound like a mighty rushing wind… And they were all filled with the Holy Spirit.” (Acts 2:1–4)
Yes, they received the gift of the Holy Spirit... not in exactly the same that we today, in the body of Christ do.
None of what you have shown means that "the divine was absent from the world" (whatever that's supposed to mean) for three days.
