(The Legal Reality Behind His Justification)
But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness. (Romans 4:5 NKJV)
Through Christ, we are declared righteous—not because of our works, but because we believe in the One who justifies the ungodly.
But how can one Man’s death justify the entire human race?
How does this legal exchange actually work in God’s courtroom?
For the love of Christ compels us, because we judge thus: that if One died for all, then all died; and He died for all, that those who live should live no longer for themselves, but for Him who died for them and rose again. (2 Corinthians 5:14-15)
These verses lay out the divine parallel:
Just as sin and death entered the world through one man (Adam), so righteousness and life come through one Man—Jesus Christ.
If He died, then all died in Him.
If He rose, then all who are in Him are raised to new life.
For us to be justified through Christ, He first had to be justified—perfectly righteous before the Father. As the firstborn among many brothers, He stands as the head of all who believe.
How Could Jesus Have No Sin?
For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him. (2 Corinthians 5:21 NKJV)
Jesus lived a completely sinless life. He was counted perfect before the Father.
Why? Because He was not conceived through human seed but by the word of the Holy Spirit in the womb of Mary. He had no earthly biological father.
In this way, the sin nature passed down through Adam never touched Him.
He stood in the pure, original authority Adam had before the fall—fully human, yet without inherited sin.
He was tempted in every way, just as we are, yet He never fell. He resisted every temptation throughout His life and died sinless.
We know death entered as punishment for sin:
Therefore, just as through one man sin entered the world, and death through sin, and thus death spread to all men, because all sinned. (Romans 5:12 NKJV)
But Jesus was not born through Adam’s line in the natural way. He was not under our fallen nature.
He faced daily temptation—like Adam in Eden—but unlike Adam, He overcame completely.
Later, the Pharisees plotted and had Him crucified.
How could someone with no sin be subject to death?
It should have been impossible. A sinless body is not liable to death.
Jesus is called the last Adam for this very reason—a new beginning for humanity.
And so it is written, “The first man Adam became a living being. The last Adam became a life-giving spirit.” (1 Corinthians 15:45)
Humanity became sinners through the first Adam.
We receive righteousness through the last Adam—Jesus.
He became the ultimate sacrifice on the altar, the Lamb of God who takes away the sin of the world.
The next day he saw Jesus coming toward him and said, “Behold, the Lamb of God, who takes away the sin of the world!” (John 1:29 ESV)
In the Old Testament, a sin offering—often a spotless lamb—was required for atonement (see Leviticus 4:32). The blood of the lamb covered the person’s sins.
Jesus fulfilled this perfectly: the sinless Lamb whose blood atones once for all.
He was betrayed, tortured, crucified, and killed—yet He had no personal sin.
His death was not for His own guilt. It was for yours.
The Plot Twist: Death Could Not Hold Him
Death comes through sin. How could death claim One who had no sin?
It couldn’t—not rightfully.
Jesus died as a ransom for our sins. In that moment, He who knew no sin was made to be sin for us.
Death took Him because our sins were placed on Him—they became His.
But when He crossed into the realm of the dead, they could not keep Him.
He was not destined for death; He entered it voluntarily for our sake.
That is why Paul taunts death itself:
O Death, where is your sting? O Hades, where is your victory? (1 Corinthians 15:55)
Jesus rose again because righteousness could not be held by death.
His resurrection proves He overcame—not by His own strength alone, but in perfect obedience and faith in the Father.
Jesus answered them, “Very truly I tell you, the Son can do nothing by himself; he can do only what he sees his Father doing…” (John 5:19 NKJV)
In the spiritual realm, everything is legal.
Jesus became our substitute: He took our sin; we received His righteousness.
Death claimed Him momentarily because of the sins placed on Him.
But once the debt was paid, death had no further claim.
He rose—vindicated, justified—and in rising, He justified all who believe in Him.
Through this one Man, the authority we lost in Adam—freedom from sin and death—was reclaimed and restored.
Now, by faith, we exercise that same authority in Christ.
He justifies you, me, and everyone who believes in Him.
The legality is simple yet profound:
One Man’s sin condemned the many (Adam).
One Man’s righteousness justifies the many (Christ).
His sinless life, substitutionary death, and victorious resurrection make it legally possible for God to declare the ungodly righteous—by faith alone.
That is how grace justifies us. Find out here why grace is more poweful…
Not by our merit, but by His perfect work.
Believe in Him, and His righteousness becomes yours—legally, eternally, irrevocably.
