I am using the parallel of the sign of Jonah and the same sign for the resurrection to emphasize the lack of faith in Jesus
The resurrection day: a test in obedience and Faith in Jesus
In John 3:16, Jesus makes it clear that we must believe in Him to be saved. How do we get to believe in Jesus? Jesus is the Messiah. We learn from the Samaritan woman that the Messiah (Jesus) is to tell us all things. Jesus does say a lot of things. But do all those who claim to believe in Jesus listen to everything that Jesus says in His position as the only Voice to hear to be saved? Not all of us listen to Jesus even when we pray in His name. When there is a doctrinal controversy or misunderstanding most of us listen to the voice of man with excuses for doing so, instead of the voice of Jesus. A classical case and point example of disobedience is, again, the 3 days and 3 nights chronology for the resurrection of Jesus.
Jesus said that He was to spend 3 days and 3 nights in the heart of the earth before He was to be risen. When we consider what we accept as arithmetically correct for the chronology of the death and resurrection of Jesus, it is obvious that a lot of Christians choose to listen to men instead of Jesus. How do they try to get away with that? Classically, they dismiss the accuracy which Jesus provided to avoid any confusion in the prophetic phrases ‘the third day', 'in three days', 'after three days' for day of the resurrection.
We read that the report about the burial and resurrection in the Gospels leads many to understand that Jesus died on a Friday and was risen early Sunday. It is not even an understanding for the resurrection day because many translations report that the resurrection occurred early on a Sunday morning while other translations report the resurrection on the first of the Sabbaths which is by definition a Saturday. Note that the [the] and [day] indicates that the article is not in the Greek manuscript but supplied by the translator. Also, consider the singular sabbath in one version and the plural sabbaths in the other translation. Which Sabbath was it: the singular seventh day sabbath or one of the other sabbaths associated with the feasts of festivals?
The believers who are cheated in the 3 days and 3 nights prophecy do take a deep look at the discrepancy showed in the two translations to find the resurrection: was the day on Saturday or on Sunday, according to the translations? If we listen to the voice of Jesus, we will look for the complete accurate 3 days and 3 nights. If we listen to the devil, we will dismiss the 3 days and 3 nights as unimportant, just as Satan dismissed the death sentence warning of God (Jesus) in Eden with excuses or false reasoning.
In the end of the sabbath, as it began to dawn toward the first [day] of the week, came Mary Magdalene and the other Mary to see the sepulchre. Matthew 28:1 KJV
But late in [the] sabbaths, at the dawning into [the] first of [the] sabbaths, Mary the Magdalene and the other Mary came to gaze upon the grave. Matthew 28:1 LITV
If Jesus was risen on a Sunday, the Sunday resurrection lacks one day and one night to fulfill the 3 days and 3 nights prophecy of Jesus. Those who listen only to Jesus will reject and not dismiss the Sunday resurrection but agree to a Saturday resurrection as reported in the sabbath resurrection translations as it is written in the Greek manuscripts.
In the contrary, to be blunt and bold as Jesus is (Matthew 7:23), if you dismiss the missing day and night to hold to the Sunday resurrection you listen to the voice of men which is the voice of Satan.
Now late on the sabbath day, as it began to dawn toward the first day of the week, came Mary Magdalene and the other Mary to see the sepulchre. Matthew 28:1 ASV
The same test of disobedience can apply to any other doctrines of disagreement between Judaism and Christianity. The Christianity of Jesus does not disagree with Judaism as Jesus signified it in Matthew 5:17-18 that Christianity is full Judaism minus its fulfillment by Jesus. What was fulfilled? It is the ceremonial portion of the Book of the Law of Moses which is fulfilled with all the feasts and their associated sabbaths.
With the fulfilment by Jesus, the feasts and their associated Sabbaths in Moses were made obsolete. We are left with the seventh day memorial Sabbath day of Jesus (God) and the remembrance of His death. Those who keep the feasts in Moses and their sabbaths are not coordinated with the teachings of Jesus. Before the advent of Jesus, those feasts and their sabbaths could be kept in Israel only and officiated by a functioning Levite priesthood. No other tribe and no other ethnicity in Israel were permitted to assume the Levitical charges of Moses. The demise of King Saul speaks of the role which God (Jesus) assigns to each of us in His Ministry to rescue as many willing men as He can.
