Why wouldn't God have come down and exacted his wrath immediately after Jesus was crucified?

I think you're a little off on the details.

Most Christian Churches believe that we are damned because of of the Fall of Man in the Garden of Eden.

There are some churches that believe the Jews were damned during the Crucifixion, but I can't find the Biblical reference right now.

Either way, it is kind of weird. It made sense to the people of 50-350 CE, but it isn't very convincing in our present day.

Found the Biblical Reference! It's Matthew 27:24-25. It was quite a controversy when Mel Gibson put it in his "Passion of the Christ," although I believe he didn't use a subtitle for that scene.

God did not threaten future generation with damnation, He threatened them with Love of Salvation, which clearly was rejected. The gift of Love failed. He forgave the crucifixion of His Own Son. There was a special symbol that seems to have escaped most eyes: Jesus' side was lanced and out flowed blood and water. That is a female symbol for the appearance of a new independent life. The amniotic sac breaks and out pours (shoots) water and blood, soon to follow is the child. Instead of taking up the flaming swords, people threw themselves and each other on cold metal blades. As far as I understand what is going on now, He is intervening again, this time with direct knowledge of the Logos -- nothing is hidden. Also, He is showing that solipsism is categorically false, that in reality, minds may perceive and may experience other minds and connect with the Mind of God. The spiritual autism is being lifted. Should Enlightenment visit a person, it is very important for the recipient to be prepared to let go of anything that comes into conflict with the Logos. One has to humble oneself in front of the Logos to let It do Its Work. It is a very powerful experience that restructures the person, to resist it can be fatal. Look at the behavior of some of the revered Saints, they did not act very appropriately after being gifted, some behavior was downright ludicrous, part of the bizarre behavior had to with the ego-Logos conflicts.

Probably for the same reasons Jesus was crucified in the first place. It’s better to concentrate on the principles of the word than examine the whys and wherefore’s of Gods inaction. God is at war with a presence established from the outset, to give him the benefit of any doubt, we would need to concede he too was at his most weakest moment, and if the Christ was destroyed in preference of the monstrous Barabbas, then maybe Gods ultimate and precise vengeance was damnation of the people to rule of the evil they voted for against his Son.

Because its a matter of faith.

If you had a physical manifestation of God on Earth in front of Millions in an indisputable historical occurrence....where would faith be?

No...the retribution came within that generation 39 years later with the destruction of Jerusalem and the temple. The vail of the temple was rent and a million Jews perished....fulfilling the prophecies in the old testament as well as those made by Jesus as recounted in the Gospels and those parts of Revelations concerned with the great fire of Rome and the first beast=Nero and the depiction of the Goddess Roma sitting on 7 hills.

Mathew 27

51And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent;

52And the graves were opened; and many bodies of the saints which slept arose,

53And came out of the graves after his resurrection, and went into the holy city, and appeared unto many.

Sounds pretty peeved to me, earthquakes, temple destruction, ghosts giving everyone the willies?

Time must pass for all his children to come down from His presents with the spiritual body and receive a physical body, to learn, experience, be tested, tempted and such. That is why the earth was created. Not even God can speed the process!

James 4:5 Do ye think that the scripture saith in vain, The spirit that dwelleth in us....

Jer 1:5 Before I formed thee in the belly I knew thee; and before thou camest forth out of the womb I sanctified thee, [and] I ordained thee a prophet unto the nations.

The "damnation" you speak of is not punishment for Jesus' death. Jesus was sent here BY his father TO die. He also died willingly to save the people on earth (and yes, that includes many of the people who killed him).

If anything, Jesus' death was to prevent God from purging the world of evil as he did with Noah.

The same reason that on the seventh day God rested.

Jesus is the Son who is God.

God rested for the salvation of the world.

Jesus came to the world for the salvation of the world.

The divine plan was that Jesus followed God the fathers will, and that Jesus was obedient, submitting to his crucifiction on the cross for your sins and mine. I go to the cross often and say Jesus cover me in your saving blood, for only then are we to be saved. That is why he is our savior, we could not enter heaven without Jesus, he paid the price for our sins. He loves us that much. But we have free will to accept him or reject him. Can you imagine what a loving God that is, to come down and be contained in a human vessel? Brother go to the cross, meditate on Jesus sufferings for us.

For the same reason He doesn't come down and do the wrath thing today when people are tortured, killed, oppressed, etc: free will.

We make the decision to hate and murder, we live with its consequences.
