The Immortality of the Soul

(Extracts from Francis Turretin, edited into modern English)

Question: Is the soul immortal by the nature of its own intrinsic construction?
Answer: We affirm.

Francis Turretin asks whether the human soul, by the way God made it, does not perish when the body dies. His answer is a careful yes. The soul is immortal, not because it exists by itself like God, but because God created it as a spiritual substance that does not break down like the body.

Below is Turretin’s reasoning, explained in clear and simple language, while keeping his careful logic.

1. What “immortal” means (and what it does not mean)

Turretin begins by making an important distinction.

• God alone is immortal by nature in the highest sense.
  God cannot die, cannot cease to exist, and depends on nothing outside Himself (1 Timothy 6:16).

• The human soul is immortal by creation, not by independence.
  The soul continues to exist after death because God made it that way and sustains it. If God withdrew His will, the soul could not exist for a moment.

So when we say the soul is immortal, we do not mean:

• the soul is eternal like God, or

• the soul exists on its own power.

We mean:

• the soul does not perish when separated from the body.

2. The soul is a spiritual substance, not a material one

Turretin argues that corruption belongs to physical things, not spiritual ones.

• The body dies because it is made of parts.

• Parts can be separated.

• What can be separated can be destroyed.

But the soul is:

• simple (not made of physical parts),

• spiritual,

• indivisible.

Because the soul has no material parts to decay or break apart, death cannot destroy it. Death separates the soul from the body, but it does not destroy the soul itself.

“Do not fear those who kill the body but cannot kill the soul.” (Matthew 10:28)

Christ Himself teaches that the soul survives bodily death.

3. The soul’s powers show it is made for ongoing existence

Turretin points to what the soul can do.

The human soul can:

• reason about eternal truths,

• reflect on itself,

• know God,

• desire everlasting happiness,

• fear eternal judgment.

These abilities go far beyond what matter can explain. Temporary, dying things do not naturally long for eternity.

“He has put eternity into man’s heart.” (Ecclesiastes 3:11)

God would not create a soul with a capacity for eternal communion with Him, only to erase it at death. The soul’s design points to continued existence.

4. Conscience assumes life after death

Turretin notes the testimony of conscience.

Even people without Scripture:

• fear judgment after death,

• feel guilt that demands future accountability,

• hope for reward or fear punishment beyond this life.

This universal awareness does not prove immortality by itself, but it fits perfectly with it. Conscience would make no sense if death ended everything.

“They show that the work of the law is written on their hearts.” (Romans 2:15)

5. Scripture clearly teaches the soul’s continued existence

Reason supports the doctrine, but Scripture settles it.

The Bible teaches that after death:

• the righteous are with the Lord (Luke 23:43; Philippians 1:23),

• the wicked are under judgment (Luke 16:22–23),

• souls cry out, worship, remember, and await resurrection (Revelation 6:9–11).

If the soul ceased to exist, these passages would be meaningless.

6. Answering objections

Objection: “Only God is immortal, so the soul cannot be”

Reply:
Yes, only God is immortal independently. But creatures can be immortal dependently, by God’s sustaining will. Angels are immortal in this sense, and so are human souls.

Objection: “The soul dies because Scripture says ‘the soul that sins shall die’”

Reply:
Death in Scripture often means separation from God, not non-existence. The soul dies spiritually through sin, and eternally through judgment, but it does not cease to exist.

7. Why this doctrine matters

Turretin never treats this as a mere theory.

If the soul is immortal, then:

• death is not the end,

• judgment is real,

• salvation is urgent,

• holiness matters now.

This truth presses every person to ask:

“What will become of my soul when my body returns to the dust?”

8. Summary in plain words

• God alone is immortal by nature.

• The soul is immortal by God’s design and sustaining power.

• The soul does not decay like the body.

• Reason, conscience, and Scripture agree.

• Death separates soul and body but does not destroy the soul.

Therefore, we affirm with Turretin:
The human soul, by its intrinsic construction as a spiritual substance created by God, is immortal and continues to exist after bodily death, awaiting resurrection and final judgment.

This doctrine humbles the sinner, sobers the careless, and comforts the believer.
