The Doctrine of Total Depravity
The Doctrine of Total Depravity
1. Defining Total Depravity and Original Sin
Total Depravity is a doctrinal position within Calvinism that asserts the pervasive corruption of human nature due to original sin, affecting every aspect of an individual's being.
To understand this, we must define Original Sin: the doctrine that as a result of Adam's fall in the Garden of Eden, all mankind is born with a sinful nature—a built-in propensity and inclination to sin that underlies every actual sin we commit.
Original sin affects us down to our core from the moment we are born. Our hearts naturally incline toward sin. Similar terms include:
Radical Corruption: Our human nature is corrupted at the root.
Moral Inability: We are spiritually incapable of doing anything to earn favor with God.
Human Brokenness: We are broken on the inside and in need of spiritual mending.
What Total Depravity Does Not Mean
Importantly, total depravity does not mean that:
Unbelievers are as wicked as they could possibly be.
Every person expresses their sinful nature to its absolute fullest extent.
Non-Christians are incapable of performing kind, altruistic, or socially beneficial acts.
Non-Christians cannot appreciate goodness, truth, or beauty.
Rather, it means that those good acts carry no spiritual merit before God. Non-Christians can adopt children, feed the hungry, and serve their communities—these are good human actions. However, apart from Christ, even our best deeds are tainted by our underlying sinful nature. As Scripture states, our righteous acts apart from faith are like "dirty rags" before God (Isaiah 64:6). They carry zero spiritual merit to earn our salvation because true merit comes from Jesus alone.
2. The Purpose of God's Law
From the New City Catechism, we ask: Can anyone keep the law of God perfectly?
Answer: Since the Fall, no mere human has been able to keep the law of God perfectly. Instead, we consistently break it in thought, word, and deed.
Sin is not just external behavior—like the Pharisees believed—it happens in our hearts, minds, words, and actions.
Romans 3:10–12: "None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one."
Did God create us unable to keep His law?
No. But because of the disobedience of our first parents, Adam and Eve, all creation is fallen. We are born in sin and guilt, corrupt in our nature, and unable to keep God’s law.
Romans 5:12: "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."
Notice the emphasis on death. Apart from Christ, we are spiritually dead—incapable of saving ourselves.
If no one can keep the law, what is its purpose?
The purpose of the law is that we may know the holy nature and will of God, recognize the sinful nature of our own hearts, and see our desperate need for a Savior. The law also teaches and exhorts believers to live a life worthy of our Savior.
Romans 3:20: "For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin."
The law acts as a mirror showing us our sin so that we look to Christ for salvation.
3. What Is Sin?
Sin is rejecting or ignoring God in the world He created, rebelling against Him by living without reference to Him, and failing to be or do what He requires in His law—resulting in our spiritual death and the disintegration of creation.
1 John 3:4: "Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness."
If God is King, sin is active treason and rebellion against His rightful authority.
4. Practical Application for Everyday Life
How does understanding total depravity affect our daily lives?
It fosters humility and repentance: Knowing I am prone to sin helps me acknowledge my faults, apologize, and ask for forgiveness—such as when I sin against my wife.
It helps me parent with grace: Understanding human nature helps me explain sin to my children. It helps me realize why kids struggle, disobey, and ultimately need Jesus just as much as adults do.
It highlights my absolute need for Jesus: Realizing I am spiritually dead apart from God eliminates any pride. I cannot save myself; I need a Savior.
5. Looking Ahead
Interestingly, both Calvinists and Arminians agree on the basic reality of total depravity—that humanity is fallen and needs salvation. Where the views differ are the questions we will address in future lessons:
Does God's grace enable a person to respond, or does God's grace effectually save someone?
Can we resist God's grace?
If all people are equally depraved, why do some come to faith while others do not?
The Gospel
While we are dead in our sins, Jesus is the Son of God who died on the cross for our sins and rose again. If you place your trust in Him, you are given new life.
