Francis Turretin carefully asked an important question:
Did
God make a covenant with Adam before the fall? And if so, what kind
of covenant was it?
Turretin answered: yes. God truly entered into a covenant with Adam. This covenant is often called the Covenant of Works or the Covenant of Life.
Turretin defended this doctrine because it helps us understand:
why Adam’s sin affected all mankind,
why Christ came as the “second Adam,”
and how salvation works in Scripture.
Without understanding the covenant with Adam, many parts of the Bible become unclear.
A covenant is a solemn agreement established by God. It includes:
parties involved,
promises,
conditions,
threats or penalties,
and outward signs or seals.
In Scripture, God often deals with man through covenants. He made covenants with:
Noah,
Abraham,
Israel,
David,
and finally the New Covenant through Christ.
Turretin argued that God also dealt with Adam by covenant from the beginning.
Some objected because the word “covenant” is not clearly used in Genesis 1–2.
But Turretin answered that the thing itself is plainly there even if the name is not immediately stated.
He argued that all the essential parts of a covenant are found in Eden.
God the Creator
Adam the representative of mankind
Adam did not stand merely as a private individual. He stood as the head of the human race.
This is why Adam’s sin affected all people.
“By one man sin entered into the world, and death by sin.” — Romans 5:12
“By the offence of one judgment came upon all men to condemnation.” — Romans 5:18
Adam acted publicly for humanity.
God promised life upon obedience.
Turretin believed this is implied in the warning:
“In the day that thou eatest thereof thou shalt surely die.” — Genesis 2:17
If disobedience would bring death, then obedience would bring life.
This life was not merely continued earthly existence, but blessed and confirmed life with God.
Scripture later speaks of this principle:
“The man which doeth those things shall live by them.” — Romans 10:5
“This do, and thou shalt live.” — Luke 10:28
The condition was perfect obedience.
Adam was commanded not to eat from the tree of the knowledge of good and evil.
“Of the tree of the knowledge of good and evil, thou shalt not eat of it.” — Genesis 2:17
This command tested whether Adam would submit to God’s authority.
Turretin emphasized that Adam was not created sinful or weak. He was upright, holy, and able to obey.
“God hath made man upright.” — Ecclesiastes 7:29
Adam had true freedom. He was able to obey, yet still capable of falling.
The penalty for disobedience was death.
This included:
physical death,
spiritual death,
separation from God,
and misery under divine judgment.
When Adam sinned, death immediately entered the world.
“The wages of sin is death.” — Romans 6:23
Turretin believed the Tree of Life served as a sign and seal of the covenant.
It visibly represented the life God promised upon obedience.
“To him that overcometh will I give to eat of the tree of life.” — Revelation 2:7
The tree itself did not give life magically. Rather, God used it as a covenant sign.
It is called the Covenant of Works because life was promised upon the condition of obedience.
Adam was not asked to earn God’s favor as though God owed him something. Even Adam’s righteousness would still have depended on God’s goodness.
But the covenant required works — that is, perfect obedience.
Turretin carefully distinguished this from the gospel covenant.
obedience came before life.
life and grace are freely given,
and good works follow as the fruit of salvation.
Yes.
Turretin strongly rejected the idea that God commanded the impossible.
Adam was created righteous and capable of obedience.
God would not threaten punishment for failure if Adam had no ability to obey.
Adam fell freely and willingly.
The blame belonged entirely to man, not to God.
“Let no man say when he is tempted, I am tempted of God.” — James 1:13
Turretin said God permitted the fall for wise and holy reasons.
God was not the author of sin. Adam sinned voluntarily.
Yet God sovereignly allowed the fall in order to reveal:
divine justice,
mercy,
grace,
patience,
and especially the glory of Christ.
Without the fall, the riches of redemption would never have been displayed.
Turretin believed this doctrine is essential because the whole gospel rests upon it.
The Bible presents Adam and Christ as two covenant heads.
“For as in Adam all die, even so in Christ shall all be made alive.” — 1 Corinthians 15:22
“The first man Adam was made a living soul; the last Adam was made a quickening spirit.” — 1 Corinthians 15:45
If Adam did not represent humanity by covenant, then Paul’s comparison with Christ loses its force.
Why are all people born sinful?
Because Adam acted as the representative head of mankind.
His guilt and corruption passed to his descendants.
“By one man's disobedience many were made sinners.” — Romans 5:19
Jesus came as the second Adam.
Where Adam failed, Christ obeyed perfectly.
Adam brought condemnation. Christ brings righteousness and life.
“For as by one man's disobedience many were made sinners, so by the obedience of one shall many be made righteous.” — Romans 5:19
Christ fulfilled what Adam failed to do.
Made with Adam before the fall
Condition: perfect obedience
Penalty: death
Promise: life
Adam represented humanity
Made through Christ after the fall
Salvation by grace through faith
Christ fulfills righteousness for His people
Eternal life is received as a gift
“For by grace are ye saved through faith.” — Ephesians 2:8
The first covenant shows man’s ruin.
The second reveals
God’s mercy in Christ.
Adam’s one sin brought death into the world.
We should never treat sin lightly.
If Adam failed under perfect conditions, fallen sinners cannot save themselves by works.
“By the deeds of the law there shall no flesh be justified.” — Romans 3:20
The first Adam ruined mankind.
The last Adam restores His
people.
Salvation is found in Christ alone.
“There is therefore now no condemnation to them which are in Christ Jesus.” — Romans 8:1
Francis Turretin taught that God truly made a covenant with Adam in the Garden of Eden.
This covenant included:
a promise of life,
a condition of perfect obedience,
a warning of death,
and Adam serving as the representative of mankind.
Adam broke this covenant and brought sin and death into the world.
But God, in mercy, sent Christ — the second Adam — who fulfilled righteousness for His people and established the Covenant of Grace.
Understanding the covenant with Adam helps us understand:
the seriousness of sin,
the justice of God,
the meaning of Christ’s obedience,
and the glory of salvation by grace alone through faith alone in Christ alone.
