Regarding the spirit, Brother Osama Bdullah's article is linked here:

I am going to go line by line, so be looking for the rest of my commentary over several updates ( might take two weeks or longer ) and you can respond after I have addressed the last line in both the links ( including the exegesis link ) you sent me:
The first link states : "GOD's Spirit came upon many people other than Jesus"
Comment: Yes, Jesus needed guidance from God's Spirit because once Jesus became totally human, He needed God's Spirit to guide Him.
The first link states : " Trinitanian Christians claim that since Jesus carried GOD's spirit, then he must be GOD himself "
Comment: Remember, I am not a Trinitarian Christian but I am not sure what is meant by "carried God's Spirit" but being guided by the Spirit of God was essential, since Jesus was fully human on earth.
The first link states : " he ( Jesus ) will delight in the fear of the LORD. "
Comment: I do believe that Jesus feared God and I interpret the word "fear" as respect because nobody delights in fear but people do delight in respecting God.
The first link states : "Here is my servant (Jesus ) whom I have chosen "
Comment: "chosen" here could be interpreted as God has free will to choose His own fully human Son or choose somebody else who is also fully human
The first link states: "Let us look at the many others who carried GOD's spirit in them in the Bible"
Comment: The same Spirit of God Who had to guide Jesus, also was present to guide others in the Bible
The first link states : "1 Samuel 16:16 "Let our lord command his servants here to search for someone who can play the harp. He will play when the evil spirit from God comes upon you, and you will feel better."
Comment: In verse 14 ( before verse 16 in the NLT bible version ) " Now the Spirit of the Lord had left Saul, and the Lord sent a tormenting spirit that filled him with depression and fear." (end of quote ).
In the verse 14, we see that the Spirit of God left and another spirit ( a tormentor, a apostate spirit ) arrived which shows that since God is everywhere,
God is also in the same place where tormenting, apostate spirits reside ( I would say, subordinate to the Devil ) and
since God is constantly interacting with apostate spirits ( since God is everywhere ) apostate spirits, even though in a state of apostasy, do obey God sometimes and
God in return lives in peace with apostate spirits.
TO BE CONTINUED ( thanks for your patience )
