"For just as Jonah was in the belly of the sea monster, for three days and three nights, so for three days and three nights the Son of Man will be in the Heart of the Earth".

Jesus states three days and three nights in entirety. Literally. Not parts thereof, in entirety, all inclusive. (3).

In John 19:31
"Since it was the day of preparation the Jews did not want the bodies left on The Cross during the Sabbath, especially because that Sabbath was a day of great solemnity. So they asked Pilate to have the legs of the crucified men broken and removed. Then the soldiers came and broke the legs of the first and of the other who had been crucified with Him. But when they came to Jesus and saw that Jesus was already dead, they did not break His legs. Instead one of the soldiers pierced his side with a spear and at once blood came out. He who saw this has testified (John) so that you all may believe his testimony is true and he knows that he tells the truth.

These things occurred so that the Scriptures may be fulfilled 'None of His bones shall be broken".

And again another passage of Scriptures says "and they will look on the One whose bones shall not be broken". And of course they were not as John says.

To the point of John's Writings and Readings "The Sabbath according to the Jews was a day of solemnity in which they wanted no-one remaining on The Cross. This was the day (Saturday originally being the Sabbath in the Middle East during Jesus' Life here on Earth) that Jesus was taken away. Friday Jesus died on The Cross. Sunday Jesus ascended into Heaven.

Now Jesus still in His Scriptures and from God has counted earlier the three days in the Heart of Earth.

When Jesus spoke to Mary Magdalene in His Tomb after dying, Jesus said to her "Now don't hold on to Me, I have not yet ascended to the Father. But go to My Brothers and say to them "I am ascending to My Father and to your Father, to My God and your God".

Mary Magdalene went and announced to the Disciples "I have seen the Lord" and she told them that He had said these things to her".

Therefore, Jesus had not Ascended into Heaven at the time (on Easter Sunday) when Jesus was speaking to Mary Magdalene despite Jesus already having been dead and in The Holy Spirit, which He always had been here on Earth anyway in a physical form as a being also.

Jesus may not have ascended into Heaven until that afternoon or night which is now known as Easter Sunday.

So we have Good Thursday with Jesus' Last Supper and His preparation prior.

Good Friday in which Jesus died on The Cross.

Easter Saturday (the Sabbath) in which the Jews would keep Holy and not work back in Jesus' days. Despite this being physically the day of burial, we must remember that Jesus had died the day before in which Jesus has in all probability counted Friday as the first day in reference to 'the Heart of the Earth', Saturday being moved into the Tomb. Sunday being in the Tomb (and Jesus may well have ascended that night) after speaking with Mary Magdalene.

What is the Heart of the Earth in which Jesus refers should be the question.

The heart of the Earth. Not the Heart of Jesus, not the heart of Heaven.

The heart of the Earth as it was back in those days and in ways today.

When our Jesus/God is 'all Love and Goodness' and when living here on Earth, what would one interpret if Jesus said back then "the heart of the Earth for three days and three nights".

Meaning 'the cruel cold hearts of man and horrible cruel Earth full of sin' who were about to torture and crucify Jesus (our Heavenly Brother and Heavenly Father).

Regardless of when Jesus was crucified, the most important thing is that He gave up His Life for us in order to be born, to live, for Jesus to have Mercy upon our Souls with sin on Earth, and to intervene saving Souls when asked, saving His World when asked if He so chooses, through His Divine Love and Mercy.

"Blessed are those who have not seen and yet have come to believe" says Jesus.
