Netzarim, Original followers of Yeshua & His 12
Lots of people have wondered the same thing! We must remember that Y'shua wasn't exactly a "human sacrifice." His body was human, but He had a Divine qnoma (literally, "underlying substance") and He chose to martyr Himself on our behalf. After all, He was the ONLY "perfect" human being who ever walked the earth, sent by YHWH Himself as His "arm" (Isaiah 53:1). There aren't too many others who can claim to have been born of a virgin or walked on water, turned water into wine, healed the sick and raised the dead and who mysteriously disappeared from a sealed tomb!
Ephesians 5:1. Be therefore imitators of Elohim as beloved children: 2. And walk in love; as the Mashiyach also has loved us and has given up himself for us, an offering and a sacrifice to Elohim, for a sweet aroma. (See also John 1:14 and 12:24; Revelation 13:8; Matthew 18:11; Luke 19:10).
Philippians 2:5. And think you so in yourselves, as Y'shua the Mashiyach also thought; 6. who, as he was in the likeness of Elohim, did not regard it sinful to be the coequal of Elohim; 7. yet disinherited himself and assumed the likeness of a servant, and was in the likeness of men and was found in fashion as a man; 8. and he humbled himself and became obedient to death, even the death of the stake. 9. Wherefore, also, Elohim has highly exalted him and given him a name which is more excellent than all names; 10. that at the name of Y'shua every knee should bow, of (beings) in heaven and on earth and under the earth; 11. and that every tongue should confess that Y'shua the Mashiyach is YHWH, to the glory of Elohim his Father.
Footnotes to both scriptures above borrowed from the AENT:
Offerings "qurbana" and sacrifices "dabekha" are two different entities. Although there are certain aspects to Mashiyach's death that are utterly unique to him (Zechariah 12:10, etc.), his death nevertheless echoes aspects of offerings and sacrifices that came before. The qurbana is the human life (nefesh) that Y'shua voluntarily offers up on the stake. The result of that offering is his blood put out on the "altar"; hence dabekha. However, this is certainly not, as some critics suggest, "human sacrifice." Rather, this indicates Y'shua's status as "Mashiyach ben Yoseph" (Messiah, son of Joseph).
Per strict accordance with Isaiah 53 and Genesis 22:8, Mashiyach ben Yoseph was required to suffer and die. After his death, the offering of himself became a sacrifice that was taken up, and he was resurrected three days later. Many of YHWH's prophets also suffered and were martyred at the hands of those who fought against the Malchut Elohim. In the case of Mashiyach, his shed blood is counted as the acceptable sacrifice, the Lamb of YHWH, which is most Set Apart unto YHWH
More that his literal birth name Y'shua (which was and is a common Hebrew name), and more than the perfect reputation that his name represents. Y'shua bears the Name of YHWH, the "name above all names"! Y'shua has the Name and reputation of the Father YHWH in him (John 17:11) and the name means "YHWH is Salvation" (Matthew 1:21).
