What Should Parents Teach Their Children About Sin?

By Al Felder

Children need to understand sin. That does not mean parents should burden young children with matters beyond their maturity. It does mean children must be taught, in age-appropriate ways, that sin is real, God defines it, and every person is accountable for his own choices.

Many people today avoid the word “sin.” They may call sin a mistake, a weakness, a struggle, a lifestyle, a personal choice, or simply being human, but parents must not let the world soften what God has spoken clearly. Sin is not merely doing something unpopular or disappointing others. Sin is doing wrong before God.

First John 3:4 says, “Whoever commits sin also commits lawlessness, and sin is lawlessness.” Sin is a violation of God’s will. It is acting without divine authority, refusing what God commands, doing what God forbids, or failing to do what God requires. Children need this understanding because they are not merely being trained to behave well. They are being taught how to live before God.

Sin Is Defined by God, Not by Man

Parents must teach children that man does not have the right to define sin for himself. A child may say, “I don’t think it is wrong.” A friend may say, “Everybody does it.” Culture may say, “That is normal now.” However, none of those answers can change the will of God.

Isaiah 5:20 warns, “Woe to those who call evil good, and good evil; Who put darkness for light, and light for darkness.” That danger is still with us. People often rename sin to make it sound harmless. Rebellion becomes independence, immodesty becomes confidence, dishonesty becomes avoiding trouble, anger becomes self-expression, selfishness becomes self-care, and false teaching becomes another viewpoint.

Parents must teach children not to accept the world’s definitions. Psalm 119:11 says, “Your word I have hidden in my heart, that I might not sin against You.” God’s word teaches us what sin is and helps protect us from it. Children need Scripture in their hearts before temptation takes root in their habits.

When parents correct a child, they should not only say, “That was wrong.” They should help the child understand why it was wrong before God. Lying is wrong because God commands truth. Disobedience is wrong because God commands children to obey parents. Cruelty is wrong because God commands love and kindness. Selfishness is wrong because God teaches service and humility. The child must learn that God’s word is the standard.

Sin Is a Choice, Not an Inherited Guilt

Children must also be taught carefully about personal responsibility. The Bible does not teach that children are born guilty of Adam’s sin. Ezekiel 18:20 says, “The son shall not bear the guilt of the father, nor the father bear the guilt of the son.” Guilt is not inherited from a parent. Each person is accountable for his own sin.

This is important because children need to understand both innocence and accountability.

Young children are not born sinners in the sense of being guilty before God, but as they grow, learn, and become capable of understanding right and wrong, they must be taught that choosing sin brings guilt. Sin is not something to blame on Adam, parents, friends, circumstances, temperament, or society.

James 1:14-15 says, “But each one is tempted when he is drawn away by his own desires and enticed. Then, when desire has conceived, it gives birth to sin.” Temptation is not the same as sin. Desire may pull strongly, but sin comes when one yields to that desire and acts against God’s will.

Children need this distinction. Being tempted to lie is not the same as lying. Feeling angry is not the same as sinning in anger. Wanting something does not automatically mean one has stolen. However, when a child chooses to disobey God’s will, that choice matters. Parents should teach children to take responsibility without teaching them false guilt.

Sin Often Begins in the Heart

Sin is seen in actions, but it often begins within. Jesus said, “For out of the abundance of the heart the mouth speaks” (Matthew 12:34). Words and actions reveal what is taking place inside. A lie may reveal fear, pride, selfishness, or a desire to escape consequences. Harsh speech may reveal anger or contempt. Disobedience may reveal stubbornness. Blame-shifting may reveal unwillingness to accept responsibility.

Parents must not train children to care only about appearances. A child may learn to look obedient while remaining rebellious in spirit. He may learn to say the right words while hiding deceit. He may learn to avoid consequences without loving what is right. That kind of training is incomplete.

God cares about the heart. Psalm 51:6 says, “Behold, You desire truth in the inward parts.” Children should learn that God wants honesty, humility, purity, reverence, and repentance within. Sin must not merely be hidden better. It must be corrected at the root.

This is why parents should ask heart-searching questions when appropriate:

Why did you lie?

Were you trying to avoid correction?

Did you want your own way?

Were you angry?

Were you thinking about what pleased God?

These questions help children learn that sin is not only about what happens outwardly. It is also about what is ruling the heart.

Sin Has Consequences

Children must learn that sin is serious because sin has consequences. Galatians 6:7 says, “Do not be deceived, God is not mocked; for whatever a man sows, that he will also reap.” A child may not always see consequences immediately, but God’s law of sowing and reaping still stands.

Some consequences happen in the home. Lying damages trust, disobedience invites correction, harsh words hurt relationships, laziness leaves work unfinished, and selfishness causes others to suffer. These consequences help children learn that sin is not harmless.

The greater consequence is spiritual. Romans 6:23 says, “For the wages of sin is death.” Sin separates man from God. It brings guilt and condemnation. Children must eventually understand that sin is not merely a family, school, or social issue. It is a soul issue.

Parents should teach this soberly, not harshly. The goal is not to crush a child with fear but to teach him the truth. Sin must not be treated lightly because God does not treat it lightly. If children grow up thinking sin is small, they will not understand why they need forgiveness.

Sin Must Not Be Excused

Children are quick to make excuses.

“I forgot.”

“I was tired.”

“He made me mad.”

“She started it.”

“I didn’t mean to.”

“I only did it because they did.”

Sometimes circumstances help explain what happened, but they do not automatically excuse sin. Parents should listen carefully and judge fairly, but they must not allow children to escape accountability by shifting blame.

Adam tried to shift the blame after he sinned. Eve also shifted blame (Genesis 3:12-13), but God still held each one accountable. Blaming others did not remove guilt.

Children must learn to say, “I did wrong.”

That statement is difficult but necessary. A child who cannot admit wrong will struggle to repent. A child who always excuses himself may grow into an adult who avoids responsibility before God and man.

Proverbs 28:13 says, “He who covers his sins will not prosper, but whoever confesses and forsakes them will have mercy.” Covering sin does not heal the soul; confession and change are required. Parents must teach children that excuses do not remove sin. Honesty, repentance, and correction are the proper path.

Sin Requires Repentance

Children should learn that when they do wrong, they must not merely feel bad. They must turn from wrong. Repentance is more than saying, “I’m sorry.” A child may say sorry because he was caught, because he wants consequences removed, or because he wants the moment to end. True repentance involves a change of heart that leads to a change of action.

Matthew 3:8 says, “Therefore bear fruits worthy of repentance.” Repentance bears fruit. If a child lies, repentance includes telling the truth. If he steals, repentance includes returning what was taken. If he speaks cruelly, repentance includes apology and changed speech. If he disobeys, repentance includes submission.

Parents should teach children to make things right whenever possible. This does not mean children will mature instantly. Growth takes time, but parents should not be satisfied with empty words. The goal is not merely to hear “sorry.” The goal is to help the child turn from sin and learn righteousness.

Repentance prepares children to understand the gospel. When they become accountable before God, they must know that sin cannot simply be ignored. It must be turned from.

Sin Shows Our Need for Christ

Parents must not teach sin without teaching hope. The Bible’s message is not only that man sins. It is that God provided salvation through Jesus Christ. Children need to understand that sin is serious, but they also need to hear that God is merciful.

Romans 5:8 says, “But God demonstrates His own love toward us, in that while we were still sinners, Christ died for us.” Christ did not die because sin was small. He died because sin was deadly, and man could not save himself.

Children should be taught the gospel as they mature. They should learn that Jesus is the Son of God, that He lived without sin, that He died for our sins, that He was buried, and that He rose again. They should learn that salvation is not earned by good behavior but received by obedient faith.

Acts 2:38 says, “Repent, and let every one of you be baptized in the name of Jesus Christ for the remission of sins.” Children must eventually understand that sin requires forgiveness, and forgiveness is found in Christ according to the gospel.

Parents should not manipulate children into a response they do not understand, but they should steadily teach them the truth so that when they do understand sin, they also understand the Savior.

Parents Must Model Confession and Repentance

Children learn how to deal with sin by watching their parents. If parents hide sin, excuse sin, blame others, refuse correction, or act as though they are never wrong, children will learn those habits. If parents confess wrong, apologize sincerely, repent, and submit to God’s word, children will learn humility.

James 5:16 says, “Confess your trespasses to one another, and pray for one another.” While parents must still maintain their role as authority figures, they should not pretend to be sinless. When a parent speaks harshly, breaks a promise, acts unfairly, or sins in some other way, he should admit it. A sincere apology from a parent can teach a powerful lesson: everyone is accountable to God.

Parents should also model daily dependence on God’s mercy. Prayer, worship, Scripture, and repentance should not be rare things in the home. Children should see that sin is taken seriously and that God’s grace is cherished.

Teaching Children to Hate Sin and Love Righteousness

The goal is not merely to make children afraid of getting caught. The goal is to help them hate sin and love righteousness. Psalm 97:10 says, “You who love the LORD, hate evil!” Love for God and hatred of evil belong together. Children should learn that sin is not a toy to play with, a friend to keep close, or a secret to protect. Sin is destructive. It dishonors God, damages the soul, and harms others.

At the same time, children should learn that righteousness is good. Obedience is good. Truth is good. Purity is good. Kindness is good. Worship is good. Serving God is good.

Parents should not present God’s commands as a joyless burden. First John 5:3 says, “For this is the love of God, that we keep His commandments. And His commandments are not burdensome.” God’s way is right, wise, and good.

Children need to learn not only what to avoid, but what to love.

Training Children to Deal Honestly With Sin

Sin must be named.

Sin must be corrected.

Sin must not be excused.

Sin must be confessed.

Sin must be repented of.

Sin must be forgiven through Christ.

Parents who teach these truths give their children a necessary foundation for life. They help children understand moral responsibility, personal accountability, repentance, forgiveness, and the need for the gospel.

A child who understands sin rightly will not treat wrongdoing as harmless. He will not blame everyone else for his choices. He will not think appearances are enough. He will learn to examine his heart, submit to God’s word, and seek mercy in the way God has provided.

Parents cannot repent for their children. They cannot obey the gospel for them. They cannot live faithfully in their place, but they can teach them what sin is. They can show them why it matters, point them to Christ, and they can train them to walk honestly before God.

Reflection Questions

1. Am I teaching my children that sin is defined by God’s word, not by feelings, culture, or personal opinion?

2. Do I help my children distinguish between temptation, mistakes, and actual sin?

3. How do I respond when my child makes excuses or shifts blame for wrongdoing?

4. Do my children see me confess wrong and repent when I sin?

5. Am I teaching my children not only to avoid sin, but to love righteousness and seek forgiveness through Christ?
