I praise your work to read the Quran and realise and "believe in the same God (Just follow the teachings of different Prophets)".But Islam and Al-Quran that brought by Prophet Muhammad was the final prophet and a complete version of life as "Islam is the way of life".
First,a prophet is essentially sent to help us understand something about God and His attributes,and to give us this knowledge that we cannot obtain by our own means.This is very essential to our understanding so that we do not mixed up in the whole realm of philosophy and theology.We have to get the correct knowledge through prophets.It would help us to avoid having divided loyalties by knowing that there is only one Creator for the entire universe.As an example of the basic call of the message of the prophets.In Chapter 21:verse 25,it says,
"Not a Messenger did we send before you (Muhammad) without this inspiration sent by Us to him;that there is no Gog but Me,so worship and serve Me."
In Chapter 11 of the Quran, you find that there are stories about different prophets.All of them say identical words to their people:"Worship God.You have no other deity but Him". So that shows that this is the unifying theme in all the messages of the prophets.In addition,to make it clear,the Quran indicates that one cannot really achieve servitude to God alone unless one shuns false gods.One verse in the Quran, Chapter 16:verse 36,says
"For We assuredly sent amongst every people a Messenger with the command:'Serve Allah (God) and shun false gods'."
The second basic mission of a prophet is to communicate to us the info. about the unseen ,because we cannot obtain info.about the unseen in the lab or by our own thinking.To document this the Quran ,in Chapter 72:verses 26-27,says,
"He (God) alone knows the unseen.Nor does He make anyone acquainted with His secret except a Messenger whom He has chosen."
So, the knowledge of the unseen is not only for God,but certain info. is also made a available to a messenger or prophet.
A third basic function of a prophet is to show us the way to tell us how to achieve salvation in this life ad the hereafter.How do we conduct our lives?What pleases God?What is our role on earth?What should our relationship be with each other?These are all things that we need a great deal of guidance about.As example of this is in the Quran in Chapter 3:verse 164,which mentions the mission of Prophet Muhammad,which was similar to the mission of other prophets:
"Sanctifying them and instructing them in scripture and wisdo,."
A fourth mission of Prophethood might surprise some people,although within the Islamic approach of integrating life it is very relevant.This mission is to participate in the struggle to establish social justice on earth.This means physically,if necessary, to participate in fighting the forces of evil oppression and exploitation.Of course, you might ask what evidence I have. We have several pieces of evidence in the Quran,but I will give you one verse. In Chapter 57:verse 25,it says,
"We (God) sent a aforetime Our Messengers with clear signs and sent down with them the Book and the Balance (of right and wrong) that men may stand forth in justice."
This shows that a prophet or messenger's participation in leading his people to fight evil and to establish justice on earth is part and parcel of his mission.These four basic points,I think, can be summarized,basically ,as true submission to God on an individual as well as a collective level.
