Hi there Limo,
God's peace be to you brother man. I'm glad that someone who can speak personally about their islamic beliefs is in the discussion.
I have read all the Koran through at least twice in its english translation. I have had muslim friends, spent time in muslim countries and am familiar with the basic teachings of Islam but of course, no I'm not knowledgeable in the way you are.
I have no problem accepting that Mohamed is a real historical man or that he probably 'wrote down' the Koran. My problem is that I believe The Bible is divinely inspired by God and as The Bible and The Koran do not speak with the same voice on many important points there is a problem. God is not a God of confusion.
Limon you ask -
“Among people who calls themselves Christian, Do you have a common understanding/agreement about the nature of Jesus a god or son of god or one of three? how the divine part is mixed with human part???? many many disagreements
First we both know, don't we, that Islam is not as united or agreed as you want to present it. Yes within Christianity there are many disagreements but the statement of faith known as the Nicene Creed that Christian Forums has linked to the home page is agreed by the vast majority of Bible believing Christians. If you read it (maybe you already have?) the question of who Jesus is is dealt with. The heart of christian salvation is much more about agreeing with God than about agreeing with others (though that of course, when it happens, is good

).
You say -
“The crucifixion story is told differently in the different gospels and very weak to the level that some "Christians" don't believe in it”
Yes each of the four gospels gives a different view of the crucifixion
but it is the same event
and in all four accounts The Lord dies a real death.
I don't see how someone who doesn't believe that Jesus Christ died on the cross for their sins can be a Christian. I know that many Muslims believe that most people in certain countries are 'Christian'. According to the Bible no-one is born a Christian, a second birth is necessary
You also ask these questions -
“Tell me, till date all who do call themselves Christians who are reading same books:
- Do you have one definition of Who is Christian?
- Do you have one defiition who is Christ?
- Do you have one definition who is god? how is he?”
for Who is a Christian? See -letter to the Romans chpt8:-
“You
,(Christians) however, are not in the flesh but in the Spirit, if in fact the Spirit of God dwells in you. Anyone who does not have the Spirit of Christ does not belong to him. 10 But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness. 11 If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you.”
for Who is Christ? see -letter to the Hebrews chpt1:-
“Long ago, at many times and in many ways, God spoke to our fathers by the prophets, 2 but in these last days he has spoken to us by his Son, whom he appointed the heir of all things, through whom also he created the world. 3 He is the radiance of the glory of God and the exact imprint of his nature, and he upholds the universe by the word of his power. After making purification for sins, he sat down at the right hand of the Majesty on high”
for Who is God? How is He? see - book of the prophet Isaiah chpt40:-
“Behold, the nations are like a drop from a bucket, and are accounted as the dust on the scales; behold, he takes up the coastlands like fine dust. 16 Lebanon would not suffice for fuel, nor are its beasts enough for a burnt offering. 17 All the nations are as nothing before him, they are accounted by him as less than nothing and emptiness. 18 To whom then will you liken God, or what likeness compare with him? It is he who sits above the circle of the earth, and its inhabitants are like grasshoppers; who stretches out the heavens like a curtain, and spreads them like a tent to dwell in; 23 who brings princes to nothing, and makes the rulers of the earth as emptiness.”
Limo the words you quote are those of The Lord Jesus speaking of Himself from the Gospel of John chpt16-
“IF answer of all above question is "No" then there is real need for the "Spirit of Truth" who shall "guide you into all the truth", "He will glorify and honor Me","take from what is Mine and will disclose it to you"
That is what Christians want, that Christ is honoured and glorified.
Excuse me I've written a lot. I wanted to ask you some questions but now is late, so next time.
Go well
