Is Jesus Almighty God?

Jesus is a god but he is not Almighty God.

No.

The Father of Jesus is the Almighty God. The Father of Jesus is the Most High (Luke 1:30-35; Ephesians 1:17).

No.

Is this "the first and the last" is the usual case of putting words in Jesus mouth or what someone else said about Jesus .

Both case will make it No.

According to John , Jesus openly declared and admitted that he said

“I can of mine own self do nothing: as I hear, I judge: and my judgment is just; because I seek not mine own will, but the will of the Father which hath sent me?” But then again, perhaps, being “omnipotent” is not a requirement to being an Almighty God?

No Jesus is not - he is the SON of Almighty God and always will be!

Of course he is called the first and last because he had a beginning and last because for all time, he saved us from sin and death and so never more does he need to do this.

Our Creator has no beginning because He has always been.

Well, both Jesus and God are called "Lord", so sometimes I am confused about this myself. But, technically, Jesus was the prophet of Christianity. Sometimes I do not understand how much more some Christians will worship Jesus more than they do God.

John 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.2 The same was in the beginning with God.

Psalm 107:20 He sent out his word and healed them, snatching them from the door of death.

Jesus is the word, and the second verse talks about how he came to heal us and die for us. it's also like water, it exist as liquid solid and gas, but they are still h20.

No here is a verse about him: "O people of the Scripture (Jews and Christians)! Do not exceed the limits in your religion, nor say of Allah aught but the truth. The Messiah 'Iesa (Jesus), son of Maryam (Mary), was (no more than) a Messenger of Allah and His Word, ("Be!" - and he was) which He bestowed on Maryam (Mary) and a spirit (Ruh) created by Him; so believe in Allah and His Messengers. Say not: "Three (trinity)!" Cease! (it is) better for you. For Allah is (the only) One Ilah (God), Glory be to Him (Far Exalted is He) above having a son. To Him belongs all that is in the heavens and all that is in the earth. And Allah is All-Sufficient as a Disposer of affairs." (4:171) here's another verse something different Say, [O believers], "We have believed in Allah and what has been revealed to us and what has been revealed to Abraham and Ishmael and Isaac and Jacob and the Descendants and what was given to Moses and Jesus and what was given to the prophets from their Lord. We make no distinction between any of them, and we are Muslims [in submission] to Him." (2:136) talking about all the original books that haven't been changed like the original torah, unchanged gospel, etc, etc.

Yeah, a little more like the Son of God. You know, like if God had a son? Not being sarcastic, just explaining the father/son kind of thing with those two. But like God, is eternal.

No, he could only walk on water and turn water into wine. Doesn't sound very almighty to me.

yes.

He & The Father are One.

There is one body & one Spirit.

There is only one God.
