A new race? The books say he died as a member of Homo sapiens sapiens. And if he died for my sins (as the saying has it) then there's nothing else I need do.
If that's your view, I respect your entitlement to it. It's not a view I can share. In my book everything is open to question, everything is for exploring, testing and, as far as may be, understanding. The bible paints a very unflattering picture of [him] as a violent, arbitrary entity ─ what on earth was the point of wishing sin on the world in the first place? What on earth is the point of sacrificing [his] son to [him]self when whatever it is [he] wanted to do could be accomplished by one snap of those omnipotent fingers?
I think with respect that this is a question better answered by Jews, no? They're the people who, the book makes very clear, God chose. The early Christian church was vastly more successful in converting pagans than Jews. no?
Genesis 17:1 When Abram was ninety-nine years old the LORD appeared to Abram, and said to him, "I am God Almighty; walk before me, and be blameless. 2 And I will make my covenant between me and you, and will multiply you exceedingly." 3 Then Abram fell on his face; and God said to him, 4 "Behold, my covenant is with you, and you shall be the father of a multitude of nations. 5 No longer shall your name be Abram, but your name shall be Abraham; for I have made you the father of a multitude of nations. 6 I will make you exceedingly fruitful; and I will make nations of you, and kings shall come forth from you. 7 And I will establish my covenant between me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you. 8 And I will give to you, and to your descendants after you, the land of your sojournings, all the land of Canaan, for an everlasting possession; and I will be their God."
9 And God said to Abraham, "As for you, you shall keep my covenant, you and your descendants after you throughout their generations. 10 This is my covenant, which you shall keep, between me and you and your descendants after you: Every male among you shall be circumcised. 11 You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you.
