My dear friend:
Your question does not bother me, on the contrary, it gives me strength to know that you are interested in knowing more about Jesus.
About your question:
The passage you mention is in Matthew 26:39 and it says:
And going a little further on, he fell on his face, praying, and saying: My Father, if it is possible, pass this glass from me; but not as I want, but as you.
Where it says that he prostrated himself, prostrating is a sign of reverence, and at that moment Jesus was praying to his Father, and he wanted to do it reverently.
This passage is a few verses before Judas Iscariot delivered him to be delivered into the hands of sinners (Matthew 26:45-47)
Jesus was praying to his Father, knowing that Judas was ready to deliver him, Jesus was praying, asking the father that the mission that had been entrusted to him (come into the world to die on the cross for our sins) pass to another, if it was the will of the father (My Father, if it is possible, pass this glass from me; however, not as I want, but as you.)
Jesus wanted to do the will of the father, not his own (but not as I want, but as you.)
Jesus was not afraid to die on the cross (and he did) all he wanted was to do the will of the father.
I hope this answers your question, if there is something you don't understand, just ask, and I will answer you, see you soon my friend.
P.S:Muslims have nothing to do with Christians, Islam rejects the Christian view that Jesus is the son of God, as well as that he was crucified, resurrected and atoned for the sins of humanity. (which is true)
