In Christ: How One Death and One Life Can Be for Many
Part 6 of 10 of Death Is Our Ultimate Problem
Opening Orientation
By now, we’ve seen that the Bible presents death as the ultimate problem, and that Jesus deals with sin through sacrifice and defeats death through resurrection.
But a crucial question still stands.
How can one person’s death and resurrection matter for anyone else? How does what happened to Jesus become relevant to people who lived centuries later? And how can Scripture say that Christ died for us without suggesting that He experienced every individual punishment?
The answer lies in one of the Bible’s most important phrases: “in Christ.”
The Central Question
What does it mean to be “in Christ,” and how does that explain how one man’s death and life can apply to many?
Key Scripture Passages (KJV)
1 Corinthians 15:21–22
“For since by man came death, by man came also the resurrection of the dead.
For as in Adam all die, even so in Christ shall all be made alive.”
Romans 5:18–19
“By the offence of one judgment came upon all men to condemnation…
so by the obedience of one shall many be made righteous.”
2 Corinthians 5:17
“Therefore if any man be in Christ, he is a new creature…”
Romans 6:4–5
“Therefore we are buried with him by baptism into death…
we shall be also in the likeness of his resurrection.”
1 Corinthians 15:20
“Now is Christ risen from the dead, and become the firstfruits of them that slept.”
Adam and Christ: Two Representative Heads
The Bible explains human history through two men.
Adam is not treated merely as an individual sinner. He is presented as the head of humanity. What happens to him happens to those who belong to him.
Paul says plainly:
“In Adam all die.”
No one personally committed Adam’s sin, yet everyone shares in its result—death. This is not because guilt is individually transferred, but because humanity exists in Adam.
Christ functions in the same way—but in the opposite direction.
“In Christ shall all be made alive.”
Christ is presented as the head of a new humanity, one defined not by sin and death, but by righteousness and life.
“For Us” Through Representation, Not Punishment Accounting
This framework explains how Scripture can say:
“The just for the unjust.”
Christ does not need to experience every individual penalty in order to act for others. He acts as the representative man, just as Adam did.
Adam’s act brought death to many.
Christ’s obedience brings life to many.
This is why the Bible emphasizes union, not transaction.
When someone is “in Christ”:
Christ’s death becomes their death to sin
Christ’s resurrection becomes their life
Christ’s victory over death becomes theirs
This is participation, not punishment transfer.
Union Explains Resurrection Sharing
Romans 6 makes this unmistakable.
Paul does not say Christ died so we don’t have to die.
He says we die with Him.
And he does not say Christ rose so we don’t have to rise.
He says we will be raised with Him.
This only makes sense if salvation is about sharing life, not avoiding penalties.
Christ the Firstfruits
Calling Christ the “firstfruits” is especially important.
Firstfruits are not replacements. They are the beginning of a harvest of the same kind. What happens to the firstfruits is what will happen to the rest.
Christ rises not as an exception, but as the pattern. His resurrection is the first expression of the life that will be given to those who are in Him.
Connection to the Larger Series
So far we’ve seen:
Death is the ultimate problem
Sin leads to death
Sacrifice deals with sin
Resurrection defeats death
Union explains how Christ’s life becomes ours
Now one final question presses forward.
If salvation is union with Christ’s life, how does a person enter that union? What role does faith play—and what role does it not play?
Put simply:
Christ saves not by absorbing every punishment, but by becoming the head of a new humanity who shares His life with those who are in Him.

We’ll look at what “through faith” really means and why faith receives life instead of paying a debt.
