Think about this, for the “New Testament” (“NT”) to have any possibility of being true, it necessitates that the Tana”ch-the Jewish Bible (TN “CH) must be true and trustworthy; otherwise, therefore, because the “NT” claims to be the fulfillment of the TN “CH, if the TN “CH were false, the “NT” must be false. – Yosef Michael and Rabbi Tovia Singer. (I also came up with this argument a few years before I heard Rabbi Singer say it. However, I do acknowledge that he also came up with the same logic.

 Bereshit (Genesis) – Chapter 17: 1-14. With emphasis on verses 8-11: “8 And I will give you and your seed after you the land of your sojournings, the entire land of Canaan for an everlasting possession, and I will be to them for a God.” 9 And God said to Abraham, “And you shall keep My covenant, you and your seed after you throughout their generations.10 This is My covenant, which you shall observe between Me and between you and between your seed after you, that every male among you be circumcised. 11 Those born in the house and those purchased for money shall be circumcised, and My covenant shall be in your flesh as an everlasting covenant.”

If the everlasting covenant could be taken away from the Jews and given to the Christians, it would be a worthless covenant. – Rabbi Tovia Singer.

The covenant is dependent upon circumcision, as you read above in the quoted TN “CH scripture. The Catholic Church forbade circumcision after forcing the Jews in Spain to convert in the 1400s. Then, during the Spanish Inquisition, later in the 1400s, they used that as one of the justifications, recognizing that those Jews (the Conversos) whom they forced to convert didn’t actually convert. Then they murdered those Conversos in horrific ways. This is also the reason why many Christians and followers of Yeshua circumcise their children, because they falsely believe Christians and their children are included in the covenant that G-d made with Avraham.

Devarim (Deuteronomy) – Chapter 13: 1-6: “1 Everything I command you that you shall be careful to do it. You shall neither add to it, nor subtract from it. 2 If there will arise among you a prophet, or a dreamer of a dream. He gives you a sign or a wonder, 3 and the sign or the wonder of which he spoke to you happens, [and he] says, “Let us go after other gods which you have not known, and let us worship them,” 4 you shall not heed the words of that prophet, or that dreamer of a dream; for the Lord, your God, is testing you, to know whether you really love the Lord, your God, with all your heart and with all your soul. 5 You shall follow the Lord, your God, fear Him, keep His commandments, heed His voice, worship Him, and cleave to Him. 6 And that prophet, or that dreamer of a dream shall be put to death; because he spoke falsehood about the Lord, your God Who brought you out of the land of Egypt, and Who redeemed you from the house of bondage, to lead you astray from the way in which the Lord, your God, commanded you to go; so shall you clear away the evil from your midst.

Did you notice that G-d refers to Himself in the singular, not the plural?

Most Christians, or followers of Yeshua (ישהוה), believe in a trinity in some form; there are different forms of the trinity. The two most common are a coequal trinity and a greater-to-lesser trinity.

Yeshayahu (Isaiah) – Chapter 43: 1-15, with emphasis on verse 10-15: 10 “You are My witnesses,” says the Lord, “and My servant whom I chose,” in order that you know and believe Me, and understand that I am He; before Me no god was formed and after Me none shall be. 11 I, I am the Lord, and besides Me there is no savior. 12 I told and I saved, and I made heard and there was no stranger among you, and you are My witnesses,” says the Lord, “and I am God. 13 Even before the day I am He, and there is no saving from My hand; I do, and who retracts it?” 14 So said the Lord, your Redeemer, the Holy One of Israel, “Because of you, I sent [you] to Babylon, and I lowered, them all with oars, and Chaldees in the ships of their rejoicing. 15 I am the Lord, your Holy One, the Creator of Israel, your King.”

Is there a necessity for a sacrifice to be forgiven for sin?

Yechezkel (Ezekiel) – Chapter 18: the whole chapter with emphasis on verses 20-23: “20 The soul that sins, it shall die; a son shall not bear the iniquity of the father, and a father shall not bear the iniquity of the son; the righteousness of the righteous shall be upon himself, and the wickedness of the wicked shall be upon himself. 21 And if the wicked man repent of all his sins that he has committed and keeps all My laws and executes justice and righteousness, he shall surely live, he shall not die. 22 All his transgressions that he has committed shall not be remembered regarding him: through his righteousness that he has done he shall live. 23 Do I desire the death of the wicked? says the Lord God. Is it not rather in his repenting of his ways that he may live?”

All non-Jews (גוי) are included in the everlasting covenant that G-d made with Noah: https://www.chabad.org/library/article_cdo/aid/5559665/jewish/The-Seven-Laws-of-Noah.htm
