For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect.For then would they not have ceased to be offered? For the worshipers, once purified, would have had no more consciousness of sins.But in those sacrifices there is a reminder of sins every year.For it is not possible that the blood of bulls and goats could take away sins.Therefore, when He came into the world, He said: “Sacrifice and offering You did not desire, But a body You have prepared for Me.In burnt offerings and sacrifices for sin You had no pleasure.Then I said, ‘Behold, I have come— In the volume of the book it is written of Me— To do Your will, O God.’”Previously saying, “Sacrifice and offering, burnt offerings, and offerings for sin You did not desire, nor had pleasure in them ” (which are offered according to the law),then He said, “Behold, I have come to do Your will, O God.” He takes away the first that He may establish the second.By that will we have been sanctified through the offering of the body of Jesus Christ once for all. - Hebrews 10:1-10

Keypurr, this passage is talking about how animal sacrifices are insufficient for purification, as it says in verse 2, if the ones who offer the sacrifice were made perfect through the sacrifices, then they wouldn't have had the "consciousness of sins," or in other words, their sin would be taken away.
Thus, a different offering had to be made, so that man could be purified. This offering had to be perfect, for only a perfect offering can make one perfect.
Verse 5 clarifies this, when Jesus (yes, Jesus is the one speaking) said, “Sacrifice and offering You did not desire, But a body You have prepared for Me.In burnt offerings and sacrifices for sin You had no pleasure.Then I said, ‘Behold, I have come— In the volume of the book it is written of Me— To do Your will, O God.’”
Keypurr, in oder for a spirit to live in a physical universe for an extended period of time, the spirit would need a physical body. Thus, when the Word (John 1:1) came to Earth (John 1:14), he needed a body to live in. So before He came to Earth, the Father prepared a body for Him, by "coming upon" Mary (Luke 1:35), and thus Jesus (the Word, the Holy One, the Son of God) was conceived (became flesh) in Mary's womb. (John 1:1,14, Luke 1:35)
The Word Himself, who is God, is the perfect sacrifice, because the only one who is perfect is God, therefore God Himself had to come to pay for the redemption of mankind. No man could do it, but a Man had to be the sacrifice to save mankind. So God came as a man, the Man, Christ Jesus, and died on the cross to pay for our sins. Any other sacrifice would not have been sufficient to pay for his own sin, let alone the sin of the whole world. Jesus Christ, the Word, God, the Son of God, the Son of Man, is the perfect mediator between God and man, because He is both fully God and fully man.
Therefore the body of Jesus Christ was the offering, that the Word who became flesh might die so that we could live, being sanctified by His offering, "once for all."
