Why did Jesus have to die?

A question Christians often skip past

People readily say that Jesus died out of love. That is true, but put that way it explains nothing. Why did he have to die? If God wanted to forgive, why not simply forgive?

That is the right objection, and it deserves better than a slogan.

First, what the word “sin” means

The word suggests a list of prohibitions: lies, theft, bad thoughts. That is not what the Bible means by it first.

In the Bible, sin describes something deeper: a posture. We are made in the image of God — the highest thing the Christian faith says about a human being, and it is true of absolutely everyone. But that image is damaged. There is in us an active resistance to God: the wish to run our own lives without him, to be our own reference point.

This is not only about what we do. The Bible says the separation precedes us: we are born into it as much as we consent to it (Romans 3:23; Ephesians 2:1-3).

It is an unpleasant thing to read. I know of no honest way to soften it.

Why forgiveness always costs someone

Here is what the objection misses.

Imagine someone wrecks your car. There are exactly two outcomes: either they pay, or you absorb the loss. There is no third path where the damage evaporates. Forgiveness never cancels a debt — it only decides who carries it.

That is true of small things and far more true of large ones. When someone betrays you and you forgive them, you yourself carry the weight of what was done. Forgiveness is always costly, and it is always costly to the one forgiving.

So when someone asks “why doesn’t God just forgive?”, the Christian answer is: that is exactly what he did. And the cross is what it cost him.

What the Bible says about the cross

It does not only say that Jesus died in solidarity with the suffering, true as that is. It says he died in our place.

• “The Lord has laid on him the iniquity of us all.” (Isaiah 53:6)
• “God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.” (2 Corinthians 5:21)
• “Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God.” (1 Peter 3:18)

This is what Christians call substitution: Jesus takes the penalty that was ours. Not as an innocent third party struck by an angry God in our place — that is a caricature, and it is false. The Christian faith holds that Jesus is God. In other words: the judge stepped down from the bench and paid the fine himself.

“God demonstrates his own love for us in this: while we were still sinners, Christ died for us.” (Romans 5:8)

What happened next

The story does not stop on Friday. The first Christians claimed, at the cost of their lives, that the tomb was empty on the third day — not in the sense of a memory kept alive, but of a body raised (1 Corinthians 15:3-8).

Then they said he ascended to the Father (Acts 1:9-11), and that he will return (1 Thessalonians 4:16; Revelation 1:7). This is not scenery: it means history is going somewhere, and injustice will not be left unanswered.

What it asks of you

Nothing that can be bought. That is the hardest part for most people to believe.

“It is by grace you have been saved, through faith — and this is not from yourselves, it is the gift of God — not by works, so that no one can boast.” (Ephesians 2:8-9)

No amount of effort, good deeds or self-improvement makes up for anything. Not because good deeds are worthless, but because they are the wrong currency. A debt already paid cannot be paid again.

What is asked comes in two movements, and they belong together:

• Trust — resting on what Jesus did rather than on your own record.
• Turning — what the New Testament calls repentance. The word is not sinister: it means changing direction. Honestly naming what is broken, and turning towards God instead of away from him.

It is not a performance to pass before being accepted. It is what being accepted looks like.

The stakes, stated honestly

The Christian faith holds that we do not stop existing. We are made to last, and only two outcomes are on offer: an eternity separated from God, or an eternity in union with him, received as a gift (Romans 6:23).

I would rather not have to write that sentence — it is easier to leave unsaid. But a site that hid the stakes from you out of politeness would not be respecting you.

And if you are not there

That is entirely normal. Nobody crosses all of this in one reading, and nobody will ask you where you stand.

If you want to move forward, many people begin with a very simple and very honest prayer: “God, if this is true, show me. I want to know.” It is a prayer God does not despise.

And if you would like to talk it through with someone, write to us. A person will read you and reply — no leaflet, no follow-up campaign, and no need to agree with anything.
