If Animal Sacrifices Couldn't Take Away Sin, Why Did God Command Them Before Christ

As I study the Bible and seek to understand God's redemptive plan, one question keeps stirring in my heart:

If the sacrifices of animals could not truly take away sins, why did God require them for so long? Why not simply tell His people to wait for Christ, the true sacrifice?

Hebrews makes a bold statement:

“It is impossible for the blood of bulls and goats to take away sins.”
— Hebrews 10:4

And yet, for centuries, the people of Israel were commanded by God to offer these animals—burnt offerings, sin offerings, peace offerings—repeatedly (Leviticus 1–7). This leads to another honest concern in my heart:
Why would God command such repeated, costly sacrifices—of bulls, goats, lambs, and doves—if they could never fully cleanse sin? These were real animals, of real value, especially in an agrarian economy. To the people, they represented food, livelihood, and wealth. Their loss was deeply felt.

Of course, I know that “the earth is the Lord’s and the fullness thereof” (Psalms 24:1), and all these creatures belong to Him. But that only makes the question more fascinating: Why did God ask His people to offer something so costly, over and over, knowing it could not finish the job?

The answer, I suspect, must be rooted in Christ. As Jesus said:

“Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill.”
— Matthew 5:17

If Christ is the fulfillment, then every command before Him—including these repeated, costly sacrifices—must point to Him. It must teach something about the weight of sin, the holiness of God, and the glory of redemption.

The sacrificial system of the Old Testament was detailed and demanding. Bulls, goats, lambs, and birds were brought to the altar day after day, year after year. The people knew the system well—but the system could not make them truly clean.

The book of Hebrews makes this point with divine clarity:

“For it is not possible that the blood of bulls and goats could take away sins.”
— Hebrews 10:4

And again:

“For the law, having a shadow of the good things to come… can never with these same sacrifices… make those who approach perfect.”
— Hebrews 10:1

These verses reveal a profound truth: the animal sacrifices were only a shadow. They were a symbol, a pointer, a rehearsal—not the real solution. They could cover sin temporarily, but they could not remove guilt permanently or transform the heart. Even King David, living under the law, understood this when he cried:

“You do not delight in sacrifice, or I would bring it; you do not take pleasure in burnt offerings. The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise.”
— Psalms 51:16–17

This shows that even then, God was pointing to something deeper than ritual: a heart humbled before Him, and a need for true atonement. The law could reveal sin, but it could not cure it. It could point to justice, but not satisfy it.

Ultimately, the animal sacrifices were never meant to be the end. They were a temporary provision, given by God, to prepare His people for the perfect sacrifice of Christ.

“But this Man [Jesus], after He had offered one sacrifice for sins forever, sat down at the right hand of God.”
— Hebrews 10:12

In Christ, we see what the sacrifices could only hint at: a spotless Lamb, willingly offered, whose blood doesn’t just cover sin—it cleanses it forever (1 John 1:7).

The limitations of animal sacrifices make sense when we realize their purpose: not to save, but to point forward—to awaken the need, and to prepare the way for Jesus.
