Well that's just it, it was NOT the will of God to offer burnt blood sacrifices for remission of sins. This was and is nothing more than a man-made innovation. All True Prophets and Messengers spoke out against this.
"They love sacrifice, they sacrifice flesh and eat it, but YHVH has no delight in them." Hosea 8:13
"All creatures are like a family of Allah: and Hu loves the most those who are the most Compassionate to Hus family." The Holy Prophet Muhammad (sal)
"The first cases to be adjudicated on the Day of Judgment will be those of bloodshed." - The Prophet Muhammad (sal)
"They shall no longer sacrifice their slaughtered beasts to the demons whom they wantonly follow. This shall be a rule binding on them and their descendants for all time." Leviticus 17:7
"I hate, I spurn your pilgrim feasts; I will not delight in your sacred ceremonies. When you present your sacrifices and offerings I will not accept them, nor look on the buffaloes of your shared offerings. Spare me the sound of your songs; I cannot endure the music of your lutes." Amos 5:21-23
"For I desire Mercy not sacrifice, and acknowledgment of YHVH rather than burnt offerings. Like Adam they have broken the covenant." Hosea 6:6-7
"The reek of sacrifice is abhorrent to me" Isaiah 1:13
"There is blood on your hands; wash yourselves and be clean." Isaiah 1:15-16
"There is no burnt-offering, no sacrifice, no oblation, no incense, no place to make offering before thee and find mercy. But because we come with contrite heart and humbled spirit, accept us...Accept our pledge of loyalty to You, for no shame shall come to those who put their trust in You." Song of the Three, Lines 15-17
"...I will hide my Eyes from you: yea, when you make your prayers, I will not hear: your hands are full of blood...put away the evil of your doings from My Eyes; cease to do evil." Isaiah 1:11-16
