Understanding Man’s Sinful Nature

Bible verses on man’s sinful nature: We are all sinners, born with an evil heart

Bad parenting greatly influences bad behavior, but Scripture is clear—our nature is sinful. Apostle Paul may be considered the greatest apostle, but he confessed to being the “worst sinner of all.”

He was, of course, referring to his “old self.” Before Christ came into his life, Paul persecuted Christians and killed many of them. Still, Paul extensively wrote the subject of man’s sinful nature in his epistles.

  • 1 Corinthians 2:14 – The ‘natural person’ cannot understand God.

We can’t be good before God on our own

We’re sinners at birth, selfish, and manipulative. Infants just need to cry to get their parent’s attention and get what they want. The reason evil does not behold us is because civil laws limit and contain our desires.

However, the godless has no problems with it. They will steal, kill, and destroy because lawlessness is their guilt. They are children of the world whose father is Satan. They cannot be changed unless Jesus takes over their lives.

For example, at the height of protest by the atheist group Black Lives Matter, the law was displaced for ideological reasons. Advocates of the Marxist movement did whatever pleased them. There were massive looting and arson that beset some cities.

Mainstream media such as CNN, MSNBC, and Time Magazine, among others, looked the other way and called it “peaceful protest,” while far-left liberals justified it as reparation.

In California, Penal Code Section 487 decriminalized offenses below $950 value. Inspired by the woke mob, California quickly became a haven of lawlessness, starting with San Francisco, where businesses left the city in troves in 2023.

No one is righteous

The quote “All evils are from lack of good knowledge” is often attributed to Adiqus, Deutsch, and the Quran. However, no one is good or righteous (Psalm 53:1–3); we all fall short (Romans 3:23-24), the reason we need Jesus.

Knowledge begins when we fear God (Proverbs 1:7). Knowledge also exposes the evil heart that has led the world astray, while the naivety of a child-like faith disarms wickedness.

Therefore, God has good reasons for warning Adam and Eve about the ‘Tree of the Knowledge of Good and Evil.’

Jeremiah 13:23
“Can an Ethiopian change the color of his skin? Can a leopard take away its spots? Neither can you start doing good, for you have always done evil.”

Matthew 15:19
From the heart come evil thoughts, murder, adultery, sexual immorality, theft, lying, and slander.

Mark 10:18
“Why do you call me good?” Jesus answered. “No one is good—except God alone. 

no one is good.


Renewing your mind daily

Man’s free will allows us to choose between doing the right thing or sinning. However, letting your sinful nature control your mind leads to death. But letting God’s Spirit control your mind leads to life and peace (Romans 8:6). Hence, do not feed your sinful nature.

Ask God to renew your heart

Even with a sinful nature, God can change our sinfulness into a heart of peace, honesty, or kindness. Ask Jesus to create in us a pure heart and renew spirit within (Psalm 51:10). When we seek God with all our heart, we shall find him (Jeremiah 29:11).

2 Corinthians 5:17
Therefore, if anyone is in Christ, the new creation has come: The old has gone, the new is here!”

Do not feed your sinful nature.

Did God choose me, or did I choose him?
Can we believe in Jesus on our own?
Why can’t I stop sinning?
How can I overcome my sinful nature?
