Was Jesus unaware of this heavenly contract?

After the last supper , Jesus (pbuh) leads his platoon/disciples, in the  middle of the night, to Gethsemane. Gethsemane  - oil press -  is a garden at the foot of the Mount of Olives in Jerusalem most famous as the place where Jesus prayed the night before his crucifixion.

He places eight of the eleven desciples at the entrance to the courtyard, commanding them : "Sit ye here,while I go and pray younder"  (Matthew 26:36).

"And he took with him peter
and the two sons of zebedee..
Then saith he unto them..
tarry ye here and watch with me.." (Matthew 26:37-38).

After placing his desciples in the proper places where they could defend him , he went and prayed alone...

"..and began to be sorrowful and very depressed. Then saith unto them, my soul is exceedingly sorrowful, even unto death..."

"And he went a little further,and fell on his face - Exactly like the Muslims does in the prayer). and prayed,saying, 'O my father , if it be possible , let this cup pass from me; nevertheless, not as I will, but as thou wilt" (Matthew 26:37-39).

"And being in an agony, he prayed more earnestly; and his sweat was , as it were , great drops of blood falling down to the ground" (Luke 22:24).

For me as a muslim , I was told that Jesus was destined to die for the sins of mankind. That he was "being prepared for this vicarious sacrifice before the foundation of the world. That even before the material universe came into being , there was a contract between "Father and son" , and that in the year 4000 A.A.(After Adam) . God himself in the form of Jesus, as the second person from the enigmatic Trinity, was to get himself  hanged to redeem mankind from the Original Sin and their actual sins.

What I don't understand is that after all this preparations ( "call to arms" in the upper room , and the masterful deployment of forces at Gethsemane , and the blood-sweating prayer to the God of Mercy for help - notice God calling God! - it appears that Jesus knew nothing about the contract for his crucifixion.

Would any Christian care to answer my question ...

Was Jesus unaware of this heavenly contract?

Judaism AND Christianity AND Islam.

In plain englsih...

As you can see , I have deliberately chosen the word "AND" instead of "Vs." to direct your attention to a hidden meaning that most people don't pay attention to.

It all comes down to the words of Allah in the Quran , where he said :

"Say (O Muhammad ): "O people of the Scripture (Jews and Christians): come to a word that is just between us and you, that we Worship none but Allâh, and that we associate no partners with him, that we erect not, from among ourselves, Lords and patrons other than Allah." if then They turn back, say ye: "Bear witness that we (at least) are Muslims (bowing to Allah.s Will)." (3:64).

If you ask anyone of us (holders of the books) how many Gods do you worship ? we will all say "ONE GOD" ... even though Jews and Muslims are clearer and closer in this matter , since Jews believe in the one God - no matter what his name is in hebrew "Jehovah" or "Yaweh" or whatever - they still believe in the one God and they don't associate partners nor claim sons to him.

Btw, the word "Son" in the Old & New Testament has a meaning that most people got lost in defining what it really means ...(this will be one of the topics of my later posts)

Anyhow , back to Christians.  Christians would still say "One God" , but if you ask about Jesus , the Holy spirit and the father you would probably get lost - no offense - but I do get lost .

Not that I'm ignorant , No not at all , I know all the ins and outs of this saying , but It just yields to a long conversation that would probably end by the christian friend telling you "This is a secret that will be revealed to you in heaven , you have to accept Jesus as your savior first in order to understand".

Anyhow , My next few posts - If I was meant to be still alive - I will discuss - in details - what are the points of similarities and differences between the three religions. With an open mind I shall think , and with an open heart I shall answer your questions & objections .

Remember, we are all sons of Adam and Eve , and remember that we SHOULD wish the best for each other.

Thank yall and till the next time ..

You better get ready , cuz its serious ; )
