Do you even have any idea what Isaiah was talking about 'stammering lips' and what that meant?
No that was not talking about mohammed, that was talking about Prophecy, Prophecying the Tongues that would fall upon the Apostles After Jesus went up to Heaven.
I will post more on this in detail later. I have a book that talks about the baptism of the Holy Spirit, and this scripture is a propecy of the Holy Spirit, because when you become Baptized of the Holy Spirit, you speak in what is called tongues. This is what stammering lips mean, its not talking about mohammed.
I will prove this later, im quite busy with some personal work right now.
God bless.
