Jesus on Anger: Sermon On The Mount | Matthew 5:21–26

Anger is a universal human experience, but Jesus calls us to confront its true nature. In His Sermon on the Mount, He addresses anger not as a fleeting emotion but as a seed that can grow into destruction if left unchecked. His teaching redirects our focus from external actions to the internal condition of our hearts, offering a path to transformation.


1. Anger as the Root of Destruction

In Matthew 5:21–22, Jesus makes a radical statement:
“You have heard that our ancestors were told, ‘You must not murder. If you commit murder, you are subject to judgment.’ But I say, if you are even angry with someone, you are subject to judgment!”

Jesus equates harboring anger in our hearts with the sin of murder. Why? Because anger destroys—spiritually, relationally, and emotionally. Like a fire, it consumes everything in its path, leading to bitterness, division, and brokenness.

The Progression of Anger

  1. Anger turns into insults.
    • Dehumanizing others with our words dishonors the image of God in them.
  2. Anger leads to contempt.
    • Contempt fractures relationships, creating barriers to love and reconciliation.

Key Reflection: Anger is a seed. Left unchecked, it grows into bitterness and destruction. Are you nurturing seeds of anger in your heart?


2. Learning About Anger From God

While human anger is often impulsive and self-serving, God’s anger is measured, just, and rooted in love. As Exodus 34:6 reveals:
“The Lord! The God of compassion and mercy! I am slow to anger and filled with unfailing love and faithfulness.”

God’s Anger vs. Our Anger

  • Our anger is often quick, disproportionate, and rooted in wounded egos.
  • God’s anger is slow, deliberate, and protective—directed against sin and evil, not people.

Illustration: God’s anger is like a parent’s outrage at a drug dealer targeting their child. It seeks to eliminate harm and restore what is good.

Even Jesus, when cleansing the temple (John 2:13–16), displayed righteous anger. But His anger was not impulsive; it was rooted in decades of witnessing corruption in the temple.

Key Reflection: Are we reflecting God’s patience and measured response, or are we quick to anger and slow to forgive?


3. What Anger Reveals About Us

Anger often serves as a window into our deeper struggles.

What Lies Beneath Anger?

  • Fear:
    Fear of losing control or being powerless often fuels anger.
    • Example: Peter’s anger in cutting off the servant’s ear (John 18:10) revealed his fear of losing Jesus.
  • Hurt:
    Anger can mask unresolved pain.
    • Example: David’s anger at Nathan’s parable (2 Samuel 12:5–7) revealed his guilt and shame over his own sin.
  • Grief:
    Unmet expectations or deep loss can manifest as anger.
    • Example: Martha’s frustration with Jesus (John 11:21) when Lazarus died revealed her grieving heart.

What Does Anger Say About Our View of God?

  • Distrust in His justice:
    We often attempt to rectify wrongs ourselves rather than trust God’s timing.
  • Frustration with His timing:
    Impatience can reveal a lack of faith in His plan.
  • Doubts about His goodness:
    Intense anger can lead us to question God’s character or even His love.

Key Reflection: Does your anger stem from trusting God too little or depending on yourself too much?


4. The Call to Reconciliation and Peace

Jesus commands us to seek reconciliation before offering our gifts at the altar:
“If you are presenting a sacrifice at the altar and you suddenly remember that someone has something against you, leave your sacrifice there at the altar. Go and be reconciled to that person. Then come and offer your sacrifice to God.” (Matthew 5:23–24)

Practical Steps to Overcome Anger

  1. Identify the Root Cause:
    • Ask: Is my anger masking fear, hurt, or grief?
  2. Reflect on God’s Patience:
    • Remember His slow-to-anger character and emulate it in your relationships.
  3. Pursue Reconciliation:
    • Resolve conflicts quickly. As Paul writes in Ephesians 4:26:
      “Don’t sin by letting anger control you. Don’t let the sun go down while you are still angry.”
  4. Trust God’s Justice:
    • Release the burden of revenge, knowing God is just and will act in His perfect timing (Romans 12:19).
  5. Practice Patience and Forgiveness:
    • Reflect on the long-suffering love of God.
