Why did Jesus die on the cross? What exactly did that accomplish?

“Penal Substitutionary Atonement” (PSA) is a theological term that describes how Jesus took the sins of mankind upon Himself when He died on the cross. God is holy and demands that sin be punished, but He chose to punish Jesus in place of guilty sinners (like you and me). His death appeased the wrath of God against sinners and it also satisfied the need for justice to occur. “Without the shedding of blood there is no forgiveness of sins” is what Hebrews 9:22 says.

• Penal. The penalty we deserved was transferred to Christ. We deserved God’s punishment in Hell because of our sin, but Jesus became our…

• Substitute. Jesus did not deserve to be punished for anything; as God in human flesh He had lived a sinless life that was pleasing to God. Instead of getting rewarded for His Holy life He, instead, become “the Lamb of God who takes away the sins of the world.”

• Atonement. A similar word is propitiation. In the Old Testament, the blood of animals was sacrificed on the altar as an atonement for sin. The English word atonement is (roughly) a combination of “at” and “one,” or to be reconciled.

Some Christians assert that the “PSA” is a relatively modern invention that didn’t exist for the first thousand years or so of the Church. But this idea is just an assertion that usually is combined with the claim that Anselm “invented” it. But the idea that Jesus died in our place as an atoning sacrifice for our sins has been taught by others throughout Church history, and more importantly, it is taught in the Bible itself.

It is also claimed that other theories of atonement are more biblical than the PSA theory. While there certainly are other aspects to what Jesus did on the cross, it must be maintained that atoning for human sin is at the core.

The most severe critics against PSA say things like: “That’s cosmic child abuse!” or “The violent death of Jesus to appease an angry God does not display any love at all! The loving God I serve would never do that!” But we must ask ourselves: What does God’s Word say? And since God is a Trinity of three persons in one, it should be understood that He Himself paid the price for the necessary punishment our sin required.
