1 - All the witnesses of the resurrection of Jesus are from hear-say. Provide me with an eyewitness and I'll become a Christian like you.
2 - Revelations come through dreams and visions and, revelations of Divine origin never come to confirm non-Jewish doctrines.
3 - The gospel of Paul, not the gospel of Jesus which was Judaism.
4 - Quite metaphorical the language.
5 - Jesus was a Jew. Those things you have put in his mind are not Jewish. There is no more than 20% in the NT that comes from Jesus or is about him.
1) But who will you count as an eyewitness? Because He is alive, I know; I've literally seen Him myself. So have a lot of the people I know personally. And I was not brought up in this faith. I'm descended from Sephardic Jews. One of my ancestors was a well known Jewish scholar.
2) I agree with you. But what you don't understand and can't perceive right now, is that much was hidden from our understanding that even PARDES, couldn't unveil, because it simply wasn't time, according to HaShem's timetable, and because it takes a portion of the same Spirit to receive from the Spirit. Properties in the creation (one of His witnesses) bear this witness as water and oil do not mix.
If HaShem is a Spirit, does it not make reasonable sense that to be able to commune with Him you would need the same make-up, a portion of that Spirit? Enter the spiritual fulfillment of Pentecost where 3000 JEWS from at least 18 nations according to scholars, received the baptism in this Spirit, with accompanying signs and wonders, which are still available today, during the 2 (thousand year) days of Pentecost. It was a wedding contract, just like Mt. Sinai was, complete with fire on the "mountains".
He spoke to Moses out of a burning bush as a prophetic sign that He was going to raise up in a Spirit man veiled in flesh and speak to those still under the bondage the literal understanding of the law carries with it, in the last days. The Hebrews were in bondage to the Egyptians (a type of the flesh, flesh as in sinful nature) because of HaShem's law and HaShem put them there.
But He took them in, so He could take them out. First they had to see what was in their own hearts, face to face, before they would cry out to Him for deliverance (from the fleshly natures as epitomized by the Egyptians). He did the same principle again in the wilderness, where He said He took them there to show them what was STILL in their own hearts. He knew what was in them, but He wanted them to know. Once again, they saw it face to face, as a golden calf made from vanity and pride, which became an idol. Vanity, pride and idolatry. A three way cord is hard to break.
3) I agree with you, Jesus was a Jew, and He participated in all the feasts, ect. But so was Paul, a self-described, Pharisee of the Pharisees who testified that he still worshipped in the manner of his fathers, nearing the end of his life. There are many things wrong with Christianity, but it's not Paul's fault. The wild olive boasted itself against the tree it was grafted into, with confusion and 56,000 sects being the fruit of that labor. I read the same books and still only see one: Jew or Gentile after the flesh, one grafted into the other, intended to be one new man, both male (Jew, representative of the male, the seed: is it any wonder He commanded circumcision of THIS part?) and female (gentile, representative of the soul, soil the seed was planted in), made He them. Sadly, they have rejected each other and so no marriage has taken place.....yet.
4) Everything in there is a multi-faceted reflection of Truth, that keeps revealing more and more the more you look at it.
5) Answered this above. Except I will say, that about 80% are quotes or references to the things in the Jewish bible, so you're stats are a bit off.
