Life is in the blood and the life that Jesus sacrificed was a human life. Jesus didn't take that human life back he was resurrected a life giving spirit, Jesus was resurrected with a spirit body not a human body.
Here some bible verses that sahow it was the blood and not the body needed for atonement. I am sure you will listen to the watchtower instead but I will give you the word of God without slick commentary like the WT does.
Hebrews 9:22 ESV /
Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins.
Leviticus 17:11 ESV /
For the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life.
Revelation 5:9 ESV /
And they sang a new song, saying, “Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation,
Hebrews 9:14 ESV /
How much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our conscience from dead works to serve the living God.
Hebrews 9:12 ESV /
He entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption.
Romans 3:25 ESV /
Whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins.
Revelation 12:11 ESV /
And they have conquered him by the blood of the Lamb and by the word of their testimony, for they loved not their lives even unto death.
Hebrews 13:20 ESV /
Now may the God of peace who brought again from the dead our Lord Jesus, the great shepherd of the sheep, by the blood of the eternal covenant,
Hebrews 10:29 ESV /
How much worse punishment, do you think, will be deserved by the one who has spurned the Son of God, and has profaned the blood of the covenant by which he was sanctified, and has outraged the Spirit of grace?
Hebrews 9:11-12 ESV /
But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation) he entered once for all into the holy places, not by means of the blood of goats and calves but by means of his own blood, thus securing an eternal redemption.
Not once do you see body and blood for forgiveness. Nowhere in the bible does it say that!
When the bible does say Jesus gave up His body, it also says that He would not allow His holy one to see corruption.
but instead of accepting tehat fact along with the word resurrection (which means to stand AGAIN) and that Jesus said He would raise His body in three days- corrupt men with minds darkened by the devil have spun homemade tales of God destroying jesus body so that is why the tomb was empty and He became an invisible spirit creature that had to manufacture bodies to prove he wasn't dead (though if His body didn't rise along with WT teaching that man has no immortal soul- Jesus satyed dead)
