LOGICAL ARGUMENT......

Muslims say.. "Christians are confused, their faith has no bases and is illogical. how can Jesus be God as well as be a messenger, no Jesus cant be two.

But is it logically possible?

Yes it is possible.

Jesus can be God as well be a messenger.
It is like a wealthy man who is chairman of a company, this person as an owner can also be a worker of the company at the same time, i.e messenger to the company he owns.........

In accounting, a business or an organization and its owners are treated as two separate identifiable parties.

This is called the entity concept .
