Why couldn't God just forgive us?

It is a fair question and it is asked by thoughtful people, often by Muslims, who find the cross strange rather than beautiful: if God is all-powerful and merciful, why the blood? Why not simply say the word?

The answer starts somewhere unexpected — with what happens when you forgive somebody.

Forgiveness always costs someone

Say a friend crashes your car. He cannot pay. You forgive him.

Notice what just happened. The damage did not evaporate. The bill still exists, and somebody is paying it: you. That is what forgiving him means — you absorb a loss that was properly his.

Now imagine he crashes it and you say “there was never any damage.” That is not forgiveness. It is pretending, and it works only for things that did not matter.

So the question is not why couldn’t God forgive without cost. There is no such thing. The question is who carries it.

Why a judge cannot simply wave it through

There is a second half, and it is the one people find harder.

Picture a judge who lets a fraudster walk because he likes him. We would not call that merciful. We would call it corrupt — and the people defrauded would be right to be furious, because their loss has been declared unimportant.

A God who shrugged at evil would be in the same position. Every atrocity that has ever happened would turn out not to matter very much. That is not a kinder God; it is one who does not take the victims seriously.

So he is caught between two things that both look like goodness: he cannot ignore what was done, and he does not want to destroy the people who did it.

What the cross is

The old illustration is still the best. The defendant owes a fine he cannot pay. The judge cannot dismiss it without ceasing to be a judge. So he takes off his robe, comes down from the bench, and pays it out of his own pocket.

The debt is paid, so justice is intact. The man walks free, so mercy is real. And the cost lands on the one person who did not incur it.

That is the Christian claim about the cross, and it is why Christians say God did not send someone else to do it. On this account it is God himself who steps down.

Isaiah 53:5KJVBut he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.

Why this is stranger than the alternatives

Every other version of the story is tidier.

A God who simply forgives is easier to explain and leaves the wrongs unaddressed. A God who simply punishes is easier still and leaves nobody standing.

Christianity claims something more awkward than either: that God did both, at his own expense, and that the point where you see most clearly how seriously he takes evil is the same point where you see how far he will go not to lose you.

That is not the design of a religion built for comfort. It is why Paul called it foolishness to the Greeks and an obstacle to his own people.

Objections answered

Isn't it unjust to punish an innocent person for someone else's crime?

It would be, if he were a third party dragged in. The Christian claim is that the judge and the substitute are the same — God is not transferring his anger onto a bystander, he is absorbing it himself. And the New Testament is careful that Jesus gives himself; nobody takes his life from him.

Why does God need blood at all? Isn't that primitive?

The word for it in the Bible is life rather than gore — blood stands for a life given up. Behind the objection is a modern instinct that guilt is a feeling to be managed rather than a debt to be settled. Anyone who has been seriously wronged tends to disagree: they do not want the offender to feel better, they want the thing put right.

Couldn't God have set up the rules differently?

The rules here are not regulations he chose and could revise. Justice is being described as part of what God is, not a policy he adopted — so “just change it” amounts to asking him to stop being himself. That is not a limit on his power any more than being unable to make a square circle is.

How to say it

Start with the crashed car

“When you forgive someone who owes you money, where does the money go?” It gets the whole principle across before any theology, and it is drawn from something they have already done.

Use the corrupt judge

“Would you call a judge merciful for letting a fraudster off because he liked him?” It turns the objection round: the God being asked for would not be good.

Say who pays

“He didn’t send someone. He came.” That is the answer to the fairness objection and it is one sentence.

Romans 5:8KJVBut God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.

Shared ground, and where traditions differ

All Christians hold

All the traditions hold that Christ’s death was for us and in our place, that it was voluntary, and that it is the ground of forgiveness — and all of them hold that it was God himself who bore it.

Roman Catholic

Holds the sacrifice of the cross as made present in the Mass, and emphasises the cross as satisfaction offered on behalf of humanity.

Eastern Orthodox

Emphasises Christ defeating death itself rather than the legal transaction — the cross and resurrection together as a rescue from corruption rather than primarily a payment.

Protestant

Generally emphasises penal substitution — Christ bearing the penalty in the sinner’s place — while holding the other pictures the New Testament uses alongside it.
