Just because you say that Christ is not your Messiah, doesn't make it so. Ask Jews who have turned to Jesus, knowing that He is their true Messiah, and you will find that knowing Him as their Messiah, for them, greatly enhances their Jewishness. Christian gentiles have been added onto Israel, as Ruth was added onto Israel through union with Boaz. Jews, in essence, are not turned into Christians upon recognizing Jesus as their true and rightful Messiah, rather it is Christian gentiles that are added onto Israel when we recognize and accept your Messiah, The King of Israel, for who He is, LORD and God.
Have you read, reread, read again and studied The Torah, prayerfully before The God of Abraham, Isaac, and Jacob, asking Him for understanding? Do you really know why you believe what you believe, and are you satisfied that you have deeply, powerfully and prayerfully sought out divine truth? Have you personally had any real and life changing intervention from Almighty God in your life? Do you love Him with all your heart, mind and soul? If you cannot say yes to these questions, than I hope you will not be satisfied until you can. Remember that Jacob wrestled with God until he received a blessing from Him. Don't be satisfied until you have received your own personal blessing from The LORD of heaven and earth!
Amen!
Oh, he isnt, there is no doubt. Not just because I say so. Our people have considered the messianic claims for 2000 years and the NT claims still do not meet the requirements of Messiah ben David. No, christianity makes a Jew a meshumad, no longer part of the Jewish people. They have the right to return and their souls are Jewish but they are not "Jews".
Gentiles have not been added but will be in the messianic age. You are not grafted in. That is a Pauline lie.
As to your questions, yes to them all. Jacob did not "wrestle with God", he wrestled with an angel. G-d does not take human form. That is a Grecco-Roman myth. I most certainly have recieved the best blessing from Hashem that any man could have. I, thanks be to the Holy One Blessed be He, left Mitzrayim.
