I responded to the first line in your OP. I have to take things in pieces. From the Wikipedia article I noticed the terms legends and folklore which is not the word of God and therefore not a reliable source for learning about God.
I believe not everyone has the gift of prophesy ie hearing God speak but I have found that God is capable of delivering a message from anyone even without thier knowledge.
I believe I am confused. Are yousaying Jesus is a dictator? I don't perceive Him that way. To me a dictator wants to manage everything but Jesus as my Master does not micro-manage. An acceptance of representatives is not necessary for salvation but He does remind us what is done to them is done...
I believe Mohammed heard from a nangel and the angel was bringing the word of God. That is enough to make him a prophet of God.
I do not believe there is anything about Mohammed in the Bible.
I believe it is because I am not on every day and I did answer eventaully. BTW I never confessed at the time of salvation. I asked Jesus to be my Lord and Savior and He answered and came into my life.
I believe there are two forms of etternal life just as there are two forms of th Kingdom of God. There is the spiritual and the physcial. John 17:3 refers to the spiritual.
I believe he proclaimed himself that but that doesn't mean God spoke to him it just means he writes about God from what he learned in the Qu'ran and the Bible and he certainly didn't get everything right any more than other interpreters.
