Sorry for the length of my response, the arguments presented to support the idea Mohammad was to be found in the Bible doesn't hold up. The best interpreter of the Bible is the Bible itself.
>Jesus repeatedly says, "I was not sent but unto the lost sheep of the house of Israel "
Jesus is saying that the Jews, the people of the Promise, were to be the first to hear the Gospel. The Jewish leadership rejected this Gospel, thus the way was opened for the Gospel to be preached those ouside the house of Israel.
Mat 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth.
Mat 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:
Mat 28:20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.
Luk 24:45 Then He opened up their mind to understand the Scriptures,
Luk 24:46 and said to them, So it is written, and so the Christ must suffer, and to rise from the dead the third day.
Luk 24:47 And repentance and remission of sins must be preached on His name to all the nations, beginning from Jerusalem.
>coming with ten thousand saints, or holy men, descending upon Makkah, bearing a fiery law (the Glorious Qur’an) is an unmistakable reference to Prophet Muhammad, peace and blessings be upon him.
Deu 33:2 And he said, The LORD came from Sinai, and rose up from Seir unto them; he shined forth from mount Paran, and he came with ten thousands of saints: from his right hand went a fiery law for them.
The word for "Saints" in this passage could just as easily refer to Angels. This would have been a better translation.
Act 7:37 This is that Moses, which said unto the children of Israel, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear.
Act 7:38 This is he, that was in the church in the wilderness with the angel which spake to him in the mount Sinai, and with our fathers: who received the lively oracles to give unto us:
"Again, when Moses on Mount Sinai desired to see the face of God Himself he was not permitted to do so, only to witness the glory of the LORD passing by: "Thou canst not see my face: for there shall no man see me, and live" (Exodus 33:20). The Lord Jesus confirmed this when he said, "No man hath seen God at any time" (John 1:18). The angels therefore brought divine information to men and women, which they could not otherwise receive because of God's holiness and man's sinfulness."

>Isaiah 42 makes a reference to this "servant of the Lord" as coming from the land of Kedar .
It does not, re-read the passage carefully.
Isa 42:10 Sing unto the LORD a new song, and his praise from the end of the earth, ye that go down to the sea, and all that is therein; the isles, and the inhabitants thereof.
Isa 42:11 Let the wilderness and the cities thereof lift up their voice, the villages that Kedar doth inhabit: let the inhabitants of the rock sing, let them shout from the top of the mountains.
This "servant of the Lord" , refered to in Isa 42:1 was Jesus. He said so himself -
Isa 42:1 Behold my servant, whom I uphold; mine elect, in whom my soul delighteth; I have put my spirit upon him: he shall bring forth judgment to the Gentiles.
Isa 42:2 He shall not cry, nor lift up, nor cause his voice to be heard in the street.
Isa 42:3 A bruised reed shall he not break, and the smoking flax shall he not quench: he shall bring forth judgment unto truth.
Isa 42:4 He shall not fail nor be discouraged, till he have set judgment in the earth: and the isles shall wait for his law.
Isa 42:5 Thus saith God the LORD, he that created the heavens, and stretched them out; he that spread forth the earth, and that which cometh out of it; he that giveth breath unto the people upon it, and spirit to them that walk therein:
Isa 42:6 I the LORD have called thee in righteousness, and will hold thine hand, and will keep thee, and give thee for a covenant of the people, for a light of the Gentiles;
Isa 42:7 To open the blind eyes, to bring out the prisoners from the prison, and them that sit in darkness out of the prison house.
Luk 4:18 The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised,
Luk 7:20 And having come to Him, the men said, John the Baptist sent us to You, saying, Are You the One coming, or should we expect another?
Luk 7:21 And in the same hour He healed many from diseases and plagues and evil spirits. And He gave to many blind ones ability to see.
Luk 7:22 And answering, Jesus said to them, Going, report to John what you saw and heard; that blind ones are seeing again, lame ones are walking about, leprous ones are being cleansed, deaf ones are hearing, dead ones are being raised, poor ones are preached the Gospel. (Isa. 35:5, 6; 61:1)
Luk 7:23 And blessed is he who is not offended in Me.
>Since Jesus (peace be upon him) indicates that the Counselor will not come unless Jesus himself, leaves, it is virtually impossible for the Counselor to be the Holy Ghost, as some Christian scholars contend.
Not so. Jesus refers to the Holy Spirit as a person, not just the manifestation. of the power of God. The Counselor was to be given to the very disciples who heard this promise from Jesus, to endow them with power to preach the Gospel.
Luk 24:45 Then He opened up their mind to understand the Scriptures,
Luk 24:46 and said to them, So it is written, and so the Christ must suffer, and to rise from the dead the third day.
Luk 24:47 And repentance and remission of sins must be preached on His name to all the nations, beginning from Jerusalem.
Luk 24:48 And you are witnesses of these things.
Luk 24:49 And, behold, I send forth the promise of My Father on you. But you sit in the city of Jerusalem until you are clothed with power from on high.
This promise was fulfilled in Acts -
Act 2:1 And when the day of Pentecost was fully come, they were all with one accord in one place.
Act 2:2 And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.
Act 2:3 And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.
Act 2:4 And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
