You have two choices with two dfferent outcomes concerning Jesus.
1. You can believe that Christians following Christianity know more about Judaism than Jews following Judaism and all sacrifices require blood to be spilt. http://bible.org/seriespage/grain-offering-leviticus-21-16-614-18-79-10-1...012-13
2. You can believe that Jews following Judaism know more about Judaism than Christians following Christianity and spilt blood is not necessary for forgiveness. http://www.jewfaq.org/qorbanot.htm
If you follow 1 then you can keep going on your current path and Jesus was necessary as a human sacrifice to appease himself as God. God loves blood, gore and guts and approves of human sacrifice.
If you follow 2 then a human sacrifice of blood was never required to obtain forgiveness and your views about Jesus need to be changed. God does not approve of human sacrifice and therefore does not approve of Jesus crucifixion as a human sacrifice of blood. "Although animal sacrifice is one means of obtaining forgiveness, there are non-animal offerings as well, and there are other means for obtaining forgiveness that do not involve sacrifices at all."
Who do you think knows more about Judaism - Christians or Jews? I think Jews do.
Then there are these verses that Christians conveniently ignore ...
Then Samuel said: ‘Has the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord? Behold, to obey is better than sacrifice, and to heed than the fat of rams.’ - 1 Samuel 15:22
Many, O Lord my God, are Your wonderful works which You have done; and Your thoughts toward us cannot be recounted to You in order; if I would declare and speak of them, they are more than can be numbered. Sacrifice and offering You did not desire; my ears You have opened; burnt offering and sin offering You did not require. Then I said, ‘Behold, I come; in the scroll of the book it is written of me. I delight to do Your will, O my God, and Your law is within my heart.’ - Psalm 40:5-8
He has not dealt with us according to our sins, nor punished us according to our iniquities. For as the heavens are high above the earth, so great is His mercy toward those who fear Him; As far as the east is from the west, so far has He removed our transgressions from us. As a father pities his children, so the Lord pities those who fear Him. For He knows our frame; he remembers that we are dust. As for man, his days are like grass; as a flower of the field, so he flourishes. For the wind passes over it, and it is gone, and its place remembers it no more. But the mercy of the Lord is from everlasting to everlasting on those who fear Him, and His righteousness to children's children. - Psalm 103:10-17
For You do not desire sacrifice, or else I would give it; you do not delight in burnt offering. The sacrifices of God are a broken spirit, a broken and a contrite heart – these, O God, You will not despise. - Psalm 51:16-17
To do righteousness and justice is more acceptable to the Lord than sacrifice. - Proverbs 21:3
What to me is the multitude of your sacrifices? says the LORD; I have had enough of burnt offerings of rams and the fat of fed beasts; I do not delight in the blood of bulls, or of lambs, or of goats. When you come to appear before me, who asked this from your hand? Trample my courts no more; bringing offerings is futile; incense is an abomination to me. New moon and sabbath and calling of convocation-- I cannot endure solemn assemblies with iniquity. Your new moons and your appointed festivals my soul hates; they have become a burden to me, I am weary of bearing them. When you stretch out your hands, I will hide my eyes from you; even though you make many prayers, I will not listen; your hands are full of blood. Wash yourselves; make yourselves clean; remove the evil of your doings from before my eyes; cease to do evil, learn to do good; seek justice, rescue the oppressed, defend the orphan, plead for the widow. -- Isaiah 1:11-17
For in the day that I brought your ancestors out of the land of Egypt, I did not speak to them or command them concerning burnt offerings and sacrifices. But this command I gave them, "Obey my voice, and I will be your God, and you shall be my people; and walk only in the way that I command you, so that it may be well with you." - Jer. 7:22-23
For I desire steadfast love and not sacrifice, the knowledge of God rather than burnt offerings. -- Hosea 6:6
I hate, I despise your festivals, and I take no delight in your solemn assemblies. Even though you offer me your burnt offerings and grain offerings, I will not accept them; and the offerings of well-being of your fatted animals I will not look upon. Take away from me the noise of your songs; I will not listen to the melody of your harps. But let justice roll down like waters, and righteousness like an ever-flowing stream. -- Amos 5:21-24
Hear what the LORD says: Rise, plead your case before the mountains, and let the hills hear your voice. Hear, you mountains, the controversy of the LORD, and you enduring foundations of the earth; for the LORD has a controversy with his people, and he will contend with Israel. "O my people, what have I done to you? In what have I wearied you? Answer me! For I brought you up from the land of Egypt, and redeemed you from the house of slavery; and I sent before you Moses, Aaron, and Miriam. "With what shall I come before the LORD, and bow myself before God on high? Shall I come before him with burnt offerings, with calves a year old? Will the LORD be pleased with thousands of rams, with ten thousands of rivers of oil? Shall I give my firstborn for my transgression, the fruit of my body for the sin of my soul?" He has told you, O mortal, what is good; and what does the LORD require of you but to do justice, and to love kindness, and to walk humbly with your God? -- Micah 6:1-4, 6-8
[Jesus said,] "Go and learn what this means, 'I desire mercy, not sacrifice.' For I have come to call not the righteous but sinners." -- Matthew 9:13
[Jesus said,] "But if you had known what this means, 'I desire mercy and not sacrifice,' you would not have condemned the guiltless." -- Matthew 12:7
If Jesus desires mercy and not sacrifice then why do Christans desire the sacrifice of Jesus and not mercy? Are Christians really following Jesus in doing so?
