Why Does God Allow Evil? What the Parable of the Weeds and Wheat Teaches Us

Few questions cut deeper than this one: if God is good and all-powerful, why does evil exist? Jesus addressed this directly in the Parable of the Weeds and Wheat, and His answer is as relevant today as it was to His first disciples.

What Is the Parable of the Weeds and Wheat?

In Matthew 13, Jesus tells the story of a farmer who plants good seed in His field. While everyone sleeps, an enemy sneaks in and sows weeds among the wheat. When the plants begin to grow, the servants notice the problem and ask if they should pull the weeds out. The farmer says no. Pulling the weeds too early risks uprooting the good wheat along with them. Instead, he instructs them to let both grow together until the harvest, when the separation will happen properly.

Jesus later explains the parable clearly to His disciples:

"The one who sowed the good seed is the Son of Man. The field is the world, and the good seed stands for the people of the kingdom. The weeds are the people of the evil one, and the enemy who sows them is the devil. The harvest is the end of the age, and the harvesters are angels." - Matthew 13:37-39 New International Version (NIV)

Is It Okay to Question God About Evil and Suffering?

Some people are taught never to question God. But Scripture does not support that view. The Psalms are filled with honest cries of "Why, Lord?" and "How long, Lord?" These are not signs of weak faith. They are expressions of genuine trust in a God who is sovereign and who can handle our hardest questions.

If we see abuse, violence, war, or famine and feel nothing, something is wrong with our hearts. As children of God and co-heirs with Christ, we share in His sufferings. Crying out to God over evil is an act of faith, not doubt.

Where Does Evil Come From?

The parable points to a clear answer. Evil does not originate with God. God created the world good. Genesis 1 records His declaration over creation, including humanity, as "very good." The problem enters through an adversary, a spiritual enemy who plants poisonous seed.

Importantly, the adversary cannot create anything. He can only corrupt what is good. He is, in that sense, a parasite. He is anti-God and anti-kingdom, and the parable frames the entire sweep of history as a spiritual conflict between the good seed and the bad.

Why Doesn't God Just Remove All Evil Now?

This is the question the servants ask in the parable, and it is the question many of us ask today. The farmer's answer is instructive. Pulling the weeds too aggressively risks destroying the wheat. When human beings try to forcibly eliminate evil through power and violence, the results are often devastating for the innocent.

History bears this out. Military campaigns aimed at wiping out evil have often produced enormous suffering among civilians, refugees, and communities of faith caught in the crossfire. As followers of Christ, we are called to pursue peace through love and through respecting the dignity of every person made in God's image.

What Does the Bible Say About God's Patience With Evil?

The key word Jesus uses in the parable is the Greek word aphete, meaning "permit" or "let them be." Remarkably, this is the same word Jesus used from the cross when He said, "Father, forgive them, for they do not know what they are doing." It is also the word behind the prayer He taught us: "Forgive us our debts as we forgive our debtors."

God's patience is not indifference. Second Peter makes this plain. God does not want anyone to perish. His patience is an expression of grace, leaving room for repentance and transformation. But that same passage is clear that a day of justice is coming.

In Luke 13, Jesus addresses a similar question when His disciples ask about a massacre and a tower collapse. His answer is sobering: we cannot always explain why specific tragedies happen, and we should be slow to judge others as deserving their suffering. Life is complicated. God knows the hearts of people. We do not.

What Does Forgiveness Have to Do With This?

The parable calls us to patience and forgiveness, and these are not passive responses. They are costly and courageous ones.

Gordon Wilson, a man from Northern Ireland, lost his 20-year-old daughter in a 1987 bombing. Her last words to him were, "Daddy, I love you." From his hospital bed, Wilson said publicly that he forgave those responsible. He went on to lead reconciliation efforts between the two sides of a bloody conflict. He is remembered not for bitterness but for grace.

Nelson Mandela, after 17 years in a violent South African prison, walked out and chose forgiveness. He understood that holding onto bitterness would be its own kind of imprisonment.

These stories reflect what the parable teaches. Forgiveness is not weakness. It is the fruit of a life shaped by the Holy Spirit, and it has the power to surprise and disarm a world bent on revenge.

How Should Christians Respond to Evil in the World?

The parable does not call us to passivity. We are still called to seek justice and love mercy. But it does give us a framework for how to respond faithfully. Three responses stand out.

Pray Without Ceasing

Jesus taught His disciples to pray, "Your kingdom come, your will be done on earth as it is in heaven." That prayer includes asking for justice, for protection from the evil one, and for forgiveness to flow in both directions. We pray for those we find difficult. We pray for those who are different from us. We do not stop.

Trust in God's Ultimate Justice

The parable ends with a harvest. Good and evil will be separated. Love will prove stronger than hate. Grace will make beauty out of ugly things. Paul writes in Galatians 6:

"Do not be deceived: God cannot be mocked. A man reaps what he sows. Whoever sows to please their flesh, from the flesh will reap destruction; whoever sows to please the Spirit, from the Spirit will reap eternal life." - Galatians 6:7-8 New International Version (NIV)

God does not forget. His covenantal love for this world remains firm. He will set things right.

Keep Looking for Grace at Work

Even in the darkest places, God's grace is producing fruit. We are called not to give up on people, even those we might be tempted to write off. The author Flannery O'Connor wrote stories that showed grace embedded in the lives of broken, unlikely people. Her story "Parker's Back" tells of a drifter who, searching for identity and worth, has a Byzantine image of Christ tattooed on His back. He is beaten for it. The story ends with blood running down the face of Jesus on a man's back. It is a picture of suffering, yes, but also of a man who found his identity in Christ despite the rejection of others. Grace reaches into unexpected places.

Life Application

This week, identify one situation in your life or in the world around you where you have been tempted toward bitterness, judgment, or the desire for revenge. Instead of acting on that impulse, choose one concrete act of patience or forgiveness. It might mean praying for someone who has wronged you. It might mean resisting the urge to make a harsh judgment about someone whose circumstances you do not fully understand. It might mean trusting God with an outcome you cannot control.

The parable calls us to be the good seed, growing faithfully even alongside difficulty, and producing fruit that reflects the character of Christ.

Ask yourself:

• Where in my life am I demanding that God act on my timeline rather than trusting His patience and sovereignty?
• Is there someone I have judged as beyond grace, and what would it look like to pray for them instead?
• Am I allowing bitterness or the desire for revenge to take root in my heart, and what would it cost me to choose forgiveness this week?

"Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up." - Galatians 6:9 New International Version (NIV)
