¹² Therefore, just as sin came into the world through one man, and death through sin, and so death spread to all men because all sinned— ¹³ for sin indeed was in the world before the law was given, but sin is not counted where there is no law. ¹⁴ Yet death reigned from Adam to Moses, even over those whose sinning was not like the transgression of Adam, who was a type of the one who was to come. – Romans 5:12-14 ESV

As Paul continues to defend the doctrine of justification by faith, he draws an interesting comparison, contrasting Adam’s sin and Jesus’ sacrificial death. It was through Adam’s one act of unrighteousness that sin came into the world. While Eve was the first one to give in to Satan’s temptation to eat of the forbidden fruit, Adam was standing by her side and was fully complicit and compliant. As the God-ordained head of his household, Adam was responsible for keeping God’s commands and protecting his family. It was to Adam that God gave the command not to eat of the tree of the knowledge of good and evil; Eve had not yet been created.

The book of Genesis records, “And the Lord commanded the man, saying, ‘You may surely eat of every tree of the garden, but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die’” (Genesis 2:16-17 ESV). In the very next verse, God decides to make Adam a companion.

Then the Lord God said, ‘It is not good that the man should be alone; I will make him a helper fit for him.’” – Genesis 2:18 ESV

So Adam was responsible for communicating God’s command to Eve and ensuring that she adhered to it. But he failed.

So when the woman saw that the tree was good for food, and that it was a delight to the eyes, and that the tree was to be desired to make one wise, she took of its fruit and ate, and she also gave some to her husband who was with her. – Genesis 3:6 ESV

The result of Adam’s actions was death, not immediate physical death, but spiritual death or separation from God. He and Eve immediately experienced shame and, for the first time, noticed that they were naked. In a sense, their eyes were opened, and they began to view the world through a different lens. Until that moment, they had not seen their nakedness as a problem. But now, they attempted to cover their nakedness with leaves. Suddenly ashamed, they tried to hide from God. But He found them and meted out punishment for their disobedience.

God cursed Adam to a life of labor accompanied by futility, ending in death.

“By the sweat of your face you shall eat bread, till you return to the ground, for out of it you were taken; for you are dust, and to dust you shall return.” – Genesis 3:19 ESV

Rather than enjoying the fruit of all the other trees that God had provided, they were cast from the garden and left to provide for themselves through back-breaking work. And, ultimately, their lives would end in death. Which is why Paul writes, “Therefore, just as sin came into the world through one man, and death through sin” (Romans 5:12 ESV).

It was Adam’s sin (original sin) that brought death into the world. Paul is comparing Adam’s one act and its result with Jesus’ one act and its subsequent outcome. He contrasts Adam’s disobedience with Jesus’ obedience. The first brought death. The second brought life. Adam’s action resulted in separation from God (spiritual death). Jesus’ action brought reconciliation and regeneration (spiritual life).

But Paul’s main point in these verses is that men had been dying (suffering the penalty for their sins) long before the law had been given to Moses.

…people sinned even before the law was given. But it was not counted as sin because there was not yet any law to break. – Romans 5:13 NLT

Mankind not only inherited death as a result of Adam’s disobedience, but they also inherited his sin nature. But their death was due to Adam’s sin, not their own. From God’s perspective, they sinned “in” Adam. The penalty for his sin was passed down to his descendants. So Paul states, “ everyone died—from the time of Adam to the time of Moses—even those who did not disobey an explicit commandment of God, as Adam did” (Romans 5:14 NLT). Long before the law was given, men sinned. They may not have sinned in the same way that Adam did, but they still faced the same penalty of death. They still experienced spiritual separation from God. Why? Because Adam “was a type of the one who was to come” (Romans 5:14 ESV).

Prior to Moses receiving God’s law on Mount Sinai, men still experienced the penalty of death for disobedience. All men knew death was inevitable and unavoidable; they just didn’t know why they had to die. They feared death because they were uncertain about what would happen next. Death was an enigma to them, and it appeared to have no purpose. Death was to be feared and avoided at all costs.

But when God gave the law, it revealed the righteousness that God demanded of mankind. It provided a non-negotiable list of God’s requirements for escaping the penalty of death. With the giving of the law, God made His righteous requirements unequivocal and non-negotiable. No longer was man allowed to dictate his own set of rules for life. Morality and justice were not subjective and left up to the opinions of fallen men; they were the province of God.

However, man’s sin nature made it impossible for him to keep God’s law. Before the law was given, man sinned in ignorance. After God’s law was made known, man sinned knowingly. Like Adam, the Israelites knew God’s commands but disobeyed anyway. They knew the consequences for disobedience, but sinned all the same.

But Paul builds on his comparison between Adam and Jesus by illustrating that God provided a way out.

The law of Moses was unable to save us because of the weakness of our sinful nature. So God did what the law could not do. He sent his own Son in a body like the bodies we sinners have. And in that body God declared an end to sin’s control over us by giving his Son as a sacrifice for our sins. – Romans 8:3 NLT

That is the gospel of God that Paul has been talking about. Adam’s disobedience brought death; Jesus’ obedience brought life. Death reigned, but through the death and resurrection of Jesus, God declared an end to sin’s control over us. Martin Luther summarizes Paul’s contrast quite succinctly.

“Christ has become a Dispenser of righteousness to those who are of Him, though they have not earned any righteousness; for through the Cross He has secured (righteousness) for all men. The figure of Adam’s transgression is in us, for we die just as through we had sinned as he did. The figure of Christ is in us, for we live just as though we had fulfilled all righteousness as He did.” – Martin Luther, Commentary on Romans

Adam’s sin did not come as a shock to God. In His providence and sovereignty, God knew that the couple He had made in His image would succumb to Satan’s temptation and rebel against Him. The incarnation of the Son of God was not a knee-jerk reaction by the Father; it was not His Plan B. The fall of man did not catch God by surprise. In fact, Paul reminds us that God’s plan of redemption had been in place even before He made the world or Adam and Eve.

All praise to God, the Father of our Lord Jesus Christ, who has blessed us with every spiritual blessing in the heavenly realms because we are united with Christ. Even before he made the world, God loved us and chose us in Christ to be holy and without fault in his eyes. God decided in advance to adopt us into his own family by bringing us to himself through Jesus Christ. – Ephesians 1:3-5 NLT

Paul reiterated this claim to his young protegé, Timothy.

For God saved us and called us to live a holy life. He did this, not because we deserved it, but because that was his plan from before the beginning of time—to show us his grace through Christ Jesus. And now he has made all of this plain to us by the appearing of Christ Jesus, our Savior. He broke the power of death and illuminated the way to life and immortality through the Good News. – 2 Timothy 1:9-10 NLT

Long before Adam was created and made the fateful decision that led to death, God had ordained the death, burial, and resurrection of His Son as the solution. Man, left to his own devices, is incapable of living up to God’s righteous standards. Sin was inevitable, and mankind’s need for a Savior was unavoidable. But God had the plan in place before the universe was formed and man was created, and “Christ came at just the right time and died for us sinners” (Romans 5:6 NLT). Adam sinned and brought death. Jesus died and brought life. Adam disobeyed God and was cursed. Jesus “redeemed us from the curse of the law by becoming a curse for us. For it is written: ‘Cursed is everyone who is hung on a tree’” (Galatians 3:13 BSB). 

The sin of Adam was restored by the last Adam.

Adam, the first man, was made from the dust of the earth, while Christ, the second man, came from heaven. Earthly people are like the earthly man, and heavenly people are like the heavenly man. Just as we are now like the earthly man, we will someday be like^[i] the heavenly man. – 1 Corinthians 14:47-49 NLT
