Before anyone becomes a Christian they are “in the world“ , they are unconverted and still in their sins. The scripture says all have sinned, just what is it that determines this ? What is that we have done that makes us sinners ? Scripture says we need Jesus to have these sins forgiven, so we need Jesus to take away whatever it is that says we are sinners. I know we are saved from our sins but what is it that calls us sinners
because that is what we need saved from. All people need saved from whatever it is that calls us sinners. People in the past, the present and the future all need saved from whatever it is that says we are sinners.
Sure, we need saved from sin but sin is the result of whatever it is that defines what sin is. What is it ?
Adam, and Eve the first sinners. God created everything good and very good so no disease or pain or death but they broke Gods one command to not eat from the tree of knowledge of good, and evil so God cursed the world in Genesis 3. All humans after them have 'sinned'. Creation was around 5500 BC. Creation . com and answers in genesis have articles about creation vs evolution biology fossils etc if someone has not looked into that already.
Romans 3:20 Therefore no one will be declared righteous in God’s sight by the works of the law; rather, through the law we become conscious of our sin.
So apparently Gods perfect law involves sacrificing animals on a temple mount temple in Judea, not wearing mixed fabrics, stoning other people to death, not eating shellfish, not once lying. So everyone has broken those laws. And it was saying even if someone followed all it still doesn't make them righteous only belief in Jesus death burial resurrection does. Eventually in Revelation 20-22 in the future in the new Jerusalem there is no more curse from Genesis 3. Believers have glorified bodies not ones that get sick and worn out like on earth, and believers life forever with God Jesus angels etc.
1 Corinthians 2 9 No eye has seen, no ear has heard, no mind has conceived what God has prepared for those who love him
1. The Origin of Human Sin — Adam’s Fall
Genesis 3 (the entire chapter)
Human sin begins when Adam and Eve disobey God.
Specific verse describing the consequence:
Genesis 3:6
“The woman took of the fruit… and ate; she also gave to her husband… and he ate.”
This act introduces sin and death into human history.
Genesis 3:17
“Because you have eaten… cursed is the ground because of you.”
2. All Humans Inherit a Sinful Nature
Psalm 51:5
“Surely I was sinful at birth, sinful from the time my mother conceived me.”
Shows sin is not just actions — it’s a condition.
Job 14:4
“Who can bring a clean thing out of an unclean? No one.”
This describes inherited impurity.
⚖️ 3. All People Commit Sin
Romans 3:23
“For all have sinned and fall short of the glory of God.”
This is the clearest universal statement.
1 Kings 8:46
“There is no one who does not sin.”
Even the Old Testament states universal sinfulness.
Ecclesiastes 7:20
“Surely there is not a righteous man on earth who does good and never sins.”
4. Adam as the Source of Human Sin
Paul’s theology directly connects all human sin to Adam’s act.
Romans 5:12
“Through one man sin entered the world, and death through sin, and in this way death came to all men, because all sinned.”
Romans 5:19
“Through the disobedience of the one man the many were made sinners.”
This explains
why we are sinners — we inherited Adam’s fallen condition.
5. Sin is Universal in the Human Heart
Jeremiah 17:9
“The heart is deceitful above all things, and desperately wicked.”
Mark 7:21–23
Jesus explains sin comes from within:
“From within, out of the heart of man, come evil thoughts… All these evils come from inside and defile a person.”
6. Humans Cannot Attain Righteousness on Their Own
Isaiah 64:6
“All our righteous acts are like filthy rags.”
Even our best deeds cannot erase our sinfulness.
⭐ Summary: Why Humans Are Sinners (Biblical Teaching)
- Adam’s original rebellion brought sin into the human race (Rom. 5:12).
- All humans inherit a sinful nature (Ps. 51:5).
- All commit personal sins (Rom. 3:23).
- The human heart is corrupted and produces evil (Jer. 17:9; Mark 7:21).
- No one is righteous by themselves (Eccl. 7:20; Isa. 64:6).
Put together:
We are sinners both by inheritance and by personal choice.
