God Is Not Fixing the Old Man

Why the Gospel Is About a New Humanity

When we hear the language of newness in Christianity, we can easily think in terms of improvement.

A new opportunity.

A new season.

A new job.

A better marriage.

A healthier habit.

A more disciplined life.

There is nothing wrong with any of those things.

But when Scripture speaks about what God is doing in Christ, it goes much deeper.

Paul does not merely say that anyone in Christ becomes an improved version of their former self.

He says:

“If anyone is in Christ, he is a new creation.”

That is a much more radical claim.

The gospel is not simply God's programme for improving old humanity.

In Christ, God begins something new.

The Problem Is Deeper Than Behaviour

If humanity's deepest problem were simply bad behaviour, then the solution would be better instruction.

Give us better rules.

Teach us better habits.

Show us better examples.

And to some extent, Scripture does all of those things.

But the Bible's diagnosis goes deeper.

Paul traces humanity's condition back to Adam.

“Through one man sin entered the world, and death through sin.”

Adam is not presented merely as the first person who happened to make a bad decision.

He becomes the representative beginning of a humanity marked by sin and death.

That is why Paul can say:

“In Adam all die.”

The problem therefore is not only that human beings occasionally do sinful things.

We belong naturally to a humanity that has been damaged at its root.

So God's answer is not simply:

“Adam's children need to behave better.”

His answer is another Head.

Another Man.

Another beginning.

The Last Adam

Paul calls Jesus:

“The last Adam.”

That title is easy to read past.

But it is extraordinary.

Jesus is not only the Saviour of individual people.

He stands at the beginning of a new humanity.

The first Adam became a living being.

The Last Adam is described as life-giving.

The contrast is deliberate.

Through the first Adam comes a humanity under death.

Through Christ comes resurrection life.

This means Christianity is not fundamentally about adding Jesus to the life we already had.

It is about receiving life from another source.

Two Humanities

Paul writes:

“As we have borne the image of the earthly, we shall also bear the image of the heavenly.”

That verse gives us an important framework.

There is the earthly man.

And there is the heavenly Man.

There is Adam.

And there is Christ.

There is the old humanity.

And there is the new.

By natural birth, we belong to Adam's family.

By new birth, we are joined to Christ.

This is why Jesus tells Nicodemus:

“You must be born again.”

He does not say:

“You need a few adjustments.”

He speaks of birth.

New life.

New origin.

New family.

God Is Not Abandoning His Original Purpose

This new creation does not mean God discarded His original intention for humanity.

Genesis begins with humanity created in God's image.

Human beings were meant to reflect God within creation.

We were created to represent His rule, character and goodness.

Sin damaged that vocation.

But God's purpose was not abandoned.

Christ comes as:

“the image of the invisible God.”

He is everything humanity was meant to be and more.

And God's saving purpose is now that those who belong to Christ become:

“conformed to the image of His Son.”

So salvation is not simply about escaping judgment.

It is the restoration of God's image-bearing purpose in humanity through Christ.

Christianity Is Therefore More Than Forgiveness

Forgiveness is essential.

Without the cross, there is no reconciliation.

But the gospel does not end with:

“Your sins are forgiven.”

It continues:

“Now become what you have been joined to.”

We are forgiven in order to live.

Reconciled in order to belong.

Born again in order to grow.

Joined to Christ in order to become like Christ.

Paul describes this transformation as moving:

“from glory to glory.”

This is not instant perfection.

It is formation.

The Church Is Evidence That Something New Has Begun

Ephesians uses remarkable language.

Christ creates:

“one new man.”

People who previously stood divided are brought together in Him.

The Church therefore is not merely an organisation built around shared beliefs.

It is intended to be evidence that a new humanity has begun.

Jew and Gentile.

Different nations.

Different histories.

Different social backgrounds.

Different families.

All brought into one household in Christ.

That is why the Church should not merely preach reconciliation.

It should embody it.

If Christ has created one new humanity, then the divisions of the old humanity cannot remain untouched.

New Does Not Mean Finished

There is another important distinction.

Being new does not mean being complete.

A newborn baby is genuinely alive.

But the baby is not mature.

The same is true spiritually.

A believer can genuinely belong to Christ and still have much growing to do.

This explains something that can otherwise be confusing.

If Christians belong to a new humanity, why are Christians still imperfect?

Because new birth begins life.

Sanctification forms maturity.

And resurrection will complete what transformation in this life has not yet finished.

Paul himself could say:

“Not that I have already attained, or am already perfected.”

The new family is real.

But it is still growing.

A New Kind of Person

This changes the question I ask about Christianity.

The question is not merely:

“Am I becoming more religious?”

Or even:

“Am I becoming more successful?”

The deeper question is:

“Is the life of Christ increasingly being formed in me?”

Am I becoming more truthful?

More loving?

More holy?

More forgiving?

More courageous?

More generous?

More self-controlled?

More like the One to whom I now belong?

Because the greatest “new” thing God offers is not a new environment for the old person.

It is new life.

A new Head.

A new family.

A new identity.

A new destiny.

The gospel is bigger than self-improvement.

God is creating a people who look like Jesus.
