I don't know what your definition of honoring Jesus is. But I will point that Jesus has the following titles in Islam:
al-Masih – “The Messiah”
Kalimatullaah – “God’s Word”*
Qawl al-haqq – “sure word”
Ruhun minhu – “a Spirit from Him”*
Nabi – “prophet”
Rasul – meaning “messenger”
Abd Allah – meaning “Servant of God”
Min al-muqareeabin – “among those who are close to God”
Wadjih – “worthy of esteem in this world and the next”
Mubarak – “blessed” as “a source of benefit for others”
(* Note that Jesus being "God's Word" and "Spirit from Him" doesn't indicate divinity).
Looks to me like Jesus is honored greatly in Islam. Islam also teaches that Jesus is the messiah, who was born of a virgin and that he would return during the end times to defeat the antichrist and establish his rule on earth. So Jesus plays a HUGE role in Islamic eschatology. Name one other religion (besides Christianity) that honors and gives so much importance to Jesus. You can't because there are none.
You repudiate the teaching that Jesus is the "son of God" and "the way the truth and the life." You also make Mahomet, a mere man who died, a superior prophet to Jesus, who was raised from the dead and ascended into heaven.
I don't think Jesus taught a faith only system of belief. He expected his followers to obey the Torah. No doubt Jesus upheld the Torah, but he didn't say "I'm keeping the Law so you don't have to".
Per Paul, "Jesus releases us from the curse of the law." For everyone who doesn't obey the Torah in its "entirety" is cursed, which would include all Gentiles without exception, and as Paul also identified, all Jews too.
But Christians don't keep the Sabbath. And Paul taught the Law no longer applies after Jesus appeared.
They don't have to keep the Sabbath. They can if their conscience obliges them to. But keeping the Sabbath won't absolve from being cursed for not keeping other aspects of the Torah. Only Jesus can redeem from the curse.
But doesn't Christianity have a set of dos and don'ts? Doesn't Christianity prescribe a way of living that's aligned to what God wills? I believe the answer is YES. The only issue is that Christianity lacks the will or means to implement it and punish those who do wrong. If everything is "spiritual" then there's no need to deal with real-world issues. If God wanted people to live by a "spiritual" religion why then did He give the Torah -- a document that covers the political, legal, social, moral aspects of society?
Christians aren't called to be airy-fairy spiritual. They are required to worship God with all their mind, soul, spirit and strength. So this would include the political, legal, social, moral aspects of society.
The issue is that Bible says nothing of Jesus' soul being eternal. In fact, the bible says nothing about the nature of souls and how they were created. But on the basis of verses like "Before me there was no God formed, and after me there shall be none" (Isaiah 43:10) we can conclude that God is the only eternal being and everyone else were created later.
True. God alone is the source of eternal life, but as Jesus pointed out, he has granted that life to his Word also, which dwells at or to or with God in eternity.
