Bodies can enter into Heaven, look at Elijah and Enoch. No, Jesus was not a Zombie, for He appeared to the eleven Apostles and many in Jerusalem. In fact John states the following in his testimony:

"Then Peter, turning around, saw the disciple whom Jesus loved following, who also had leaned on His breast at the supper, and said, “Lord, who is the one who betrays You?”, Peter, seeing him, saith to Jesus, “But Lord, what about this man?” Jesus said to him, “If I will that he remain till I come, what is that to you? You follow Me.” Then this saying went out among the brethren that this disciple would not die. Yet Jesus did not say to him that he would not die, but, “If I will that he remain till I come, what is that to you?” This is the disciple who testifies of these things, and wrote these things; and we know that his testimony is true. And there are also many other things that Jesus did, which if they were written one by one, I suppose that even the world itself could not contain the books that would be written. Amen." John 21:20-25

Jesus was not a zombie. That is absurd. Yes, when we die we are judged. However, before Jesus died, the souls of the good and the evil entered into Sheol. This is where Jesus entered, and rescued from Sheol the souls of Adam, Eve, Abraham, Isaac, Jacob and all the prophets and all that believed in Him. Jesus gave the dead the chance to be forgiven. And He judged the dead. At that point the gates of Heaven were open to Man and Woman alike.

Then Jesus rose from the dead and appeared to His Apostles and many in Jerusalem. Both friend and enemy. The Jews did bring charges against Christ and tried and convicted Him, they sentenced Him to death. They even got authority from the Romans to kill Him. However, neither the Romans nor the Jews could kill Him. Then by His own command, He died. This death changed the religion forever. Now He spread the Good News to the underworld or Sheol. And those who believed in Him were welcomed into heaven.

At this point if you want to get scientific, Sheol became Hell or Hades. For Hades or Hell is the place where souls that do evil reside. The Book of Enoch sheds some light on this where, Enoch describes how God turned the Nephilim against each other. But since the creature of the nephilim was an abomination, for these creatures were part man, part woman, and part Angel, thier souls can never enter into heaven. For this reason, these spirits are today known as demons. These demons follow their father the devil, and seek to devour the souls of the righteous and enslave the evil ones of this earth.

One day, as the Apostle John points out in Revelations, just as the prophet Daniel points out, God will throw Satan, Hades, and Hell into the eternal pool of fire, the second death.

A zombie is an animated deceased body, not a living being. And if you research deep in the myth of the zombie you will find that a zombie is not resurrected but animated therefore the undead. The undead is a term that witches, warlocks, magicians, and sorcerers use to describe such a phenomenon. By reading Enoch, we find that the rebellious angels taught the innocent mankind as well as the abomination offspring(Nephilim) certain spheres of taboo knowledge. Among these sphere of taboo knowledge, sorcery, nor magic, but sorcery, astrology, astronomy, weapon making, and the art of war, is taboo. The reason that this knowledge is taboo, is because this knowledge leads a creature in defying God's Law, the Law of Moses. Each of the deadly sins are a requirement of this knowledge. But through Jesus Christ, one may break the hold of the demons and eventually or immediately stop committing these sins.

By the three days does not mean 72 hours, three days to us living in the modern world means 72 hours, but for the ancients it means Friday, Saturday, and Sunday. Three days. Just like the first day of the week is Sunday, not Monday.

Is it not written in the Book of Jude:
"But I want to remind you, though you once knew this, that the Lord, having saved the people out of the land of Egypt, afterward destroyed those who did not believe. And the angels who did not keep their proper domain, but left their own abode, He has reserved in everlasting chains under darkness for the judgment of the great day; as Sodom and Gomorrah, and the cities around them in a similar manner to these, having given themselves over to sexual immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire.

Likewise also these dreamers defile the flesh, reject authority, and speak evil of dignitaries. Yet Michael the archangel, in contending with the devil, when he disputed about the body of Moses, dared not bring against him a reviling accusation, but said, “The Lord rebuke you!” But these speak evil of whatever they do not know; and whatever they know naturally, like brute beasts, in these things they corrupt themselves. Woe to them! For they have gone in the way of Cain, have run greedily in the error of Balaam for profit, and perished in the rebellion of Korah" Jude 1:5-11

For the ancients, especially the Jewish thought, a single day was from sundown of the previous day to sundown of the current day {"Evening (night time) and morning (day time) were the...day"}.

Concerning the 3-days and 3-nights:
Luke 23:55-56 says that after the women saw where Christ had been laid, they returned to prepare spices and ointments and rested the Sabbath day...i.e. they PREPARED the spices BEFORE the Sabbath.

But Mark 16:1 says that the women BOUGHT their spices AFTER the Sabbath.

Question: How could the women prepare any spices before they had bought them?

This is an unsolvable conundrum unless one is aware of the Jewish Feasts or more correctly, the "Lord's Feasts" as outlined in Chapter 23 of Leviticus.

Also, as the English translators of the New Testament knew nothing of the Jewish festivals (the Lords feasts), they translated incorrectly Matthew 28:1. The Geek Interlinear correctly translates it: "But late of the SabbathS (note plural)..."

This is in accord with the Lord's Festivals for during Passover week there were two Sabbaths before the 1st day of the week and one Sabbath a couple days after that. The Lord's Feast spring festivals were:
1. Passover Day (Nisan 14th)
2. Unleavened Bread (Nisan 15th-a High Day or a High Sabbath...the one John refers to in his book chapter 19:31.

Then there was the regular Saturday Sabbath--this is not a Lord's Feast day.

3. First Fruits...the first day of the week following the SabbathS of Passover week.
4. The on the 7th day following Nisan 15 (a High Sabbath day) on the 22nd of Nisan was another high Sabbath day.

So, How could the women prepare their spices BEFORE the Sabbath yet buy them AFTER the Sabbath? They couldn't unless...we are talking of more than one Sabbath as a correct translation of Matthew 28:1 indicates:
a. The women bought their spice AFTER the high Sabbath and prepared them BEFORE the regular Saturday Sabbath.
b. Then the question remains: On which day of the week could anyone buy and prepare them for no buying-selling-or work could be done on any Sabbath?
c. The most obvious answer to this question would be Friday(the 16th of Nisan) as it would fall between the High Sabbath (Nisan 15) and the regular weekly Sabbath, the 17th of Nisan.

The proper chronology of events is:
1. Wednesday: the Passover lamb (Christ) had to be buried before sundown on the 14th (Wednesday) as at sundown on the 14th the High Sabbath (15th of Nisan) began.
2. Thursday, the 15th of Nisan, was a High Sabbath...no buying or selling allowed.
3. Friday, the 16th of Nisan was a common work day...spices and ointment could be bought and prepared on this day.
4. Saturday, the 17th was a Sabbath...no buying and selling allowed.
5. Just after sundown on the 17th, as the 18th (1st day of the week) began Christ arose as the First Fruit of the resurrection.
