Reflecting on Jesus’ Teaching in Matthew 5:28
Have you ever caught yourself thinking something you’d never say out loud? Or maybe you felt proud of avoiding a bad action. Your thoughts drifted in directions you’d rather not admit. I know I have. These moments remind me of the powerful teachings of Jesus, especially in Matthew 5:28.
What Did Jesus Say in Matthew 5:28?
Jesus taught many life-changing lessons during His time on earth. One of the most challenging comes from His Sermon on the Mount, where He says:
“But I tell you that anyone who looks at a person lustfully has already committed adultery with them in their heart.”
This is a radical idea. Jesus isn’t just concerned about what we do on the outside. He cares about what happens inside us, in the secret places of our hearts and minds.
Beyond Actions: God Cares About Our Thoughts
Have you ever thought that as long as you didn’t do something wrong, you were in the clear? Many people in Jesus’ time believed just that. The religious leaders taught that following God’s law was about outward behavior—don’t steal, don’t hurt others, don’t commit adultery. But Jesus challenged this thinking. He said our internal world—our thoughts, motives, and desires—matters just as much.
Think back to a time when you did the right thing, but your heart wasn’t in it. Did you find yourself wondering if that was enough? Jesus invites us to be honest with ourselves and with God. We should seek purity not just in our actions but also in our inner lives.
Why Is This Teaching Important?
- God sees our hearts. He knows what we think, feel, and desire, even if we never act on it or say it aloud.
- It calls us to authenticity. Are we truly who we seem to be, or are we just putting on a good show?
- It redefines sin. Sin isn’t just breaking rules. It’s anything that separates us from God. This includes the thoughts we harbor and the attitudes we nurture.
The Heart of the Law: Not Just Rules, But Real Change
Jesus didn’t come to abolish the law, but to show its deeper purpose. God’s hope is not just that we avoid bad deeds. He hopes we become people who love Him and others from the inside out. Have you ever tried to change a habit, only to realize it starts with changing your mindset? Jesus teaches that true obedience starts within.
Sin Begins in the Heart
Jesus points out that sin isn’t just about what we do. It starts with what we let grow in our thoughts and hearts. For example, even if someone never cheats, nurturing fantasies is already a step away. These intentions take us from the trust and love God desires for us.
Think about this: How would your life change if you paid as much attention to your thoughts? How would it change if you focused as much on your actions?
How Does This Apply to Us Today?
Let’s get practical. Here are some ways these teachings can shape our daily lives:
- Notice your thoughts. When you catch yourself thinking something unhelpful, pause and reflect. Consider how you can redirect your focus to love. Emphasize kindness or hope as alternatives.
- Ask God for help. Have you ever tried praying about your thoughts? God cares about our inner struggles as much as our outer challenges. Invite Him into your thought life.
- Be mindful of what you consume. Are there shows, music, or websites that tend to steer your mind in unhealthy directions? What might change if you chose content that encourages and uplifts you?
- Talk with someone you trust. Who could you open up to when you’re struggling? Sometimes a friend, mentor, or family member can give the encouragement and perspective we need.
Can you remember a time when a simple change in thought made a big difference in your day? What helped you make that change?
Why Are Lustful Thoughts So Serious?
In Jesus’ culture, adultery was considered a major offense. But Jesus wants us to recognize the power of thoughts. They can shape our actions. They can affect our relationships. Thoughts can even change the direction of our lives.
- Lustful thoughts often lead to actions we might regret.
- They can create unrealistic expectations and hurt relationships.
- They leave us feeling distant from God and others.
- Most importantly, they pull our focus away from love and respect.
What do you do when you notice thoughts that could harm your relationships or your sense of peace?
Victory Over the Desires of the Heart
Overcoming unwanted desires isn’t easy—it often takes hard work and honest self-reflection. Sometimes, it requires making tough choices, like stepping away from certain situations or habits. But remember: God provides grace, strength, and new beginnings.
Can you think of a habit or thought pattern that you’ve overcome with God’s help? What made the difference for you?
Tender Mercy and Forgiveness
Even when we stumble, God extends mercy and forgiveness. We aren’t defined by our failures—each day holds the promise of a fresh start. Jesus’ teaching isn’t meant to make us feel hopeless, but to call us to seek real change with God’s loving help.
- God wants to rescue us from unhealthy patterns, not leave us stuck in them.
- His grace empowers real transformation.
- No matter how many times we fall, we can come to God for forgiveness and renewal.
What helps you accept God’s forgiveness and move forward after a setback?
Practical Steps for a Pure Heart
- Check in: Are your thoughts loving and respectful? If not, how might you shift them?
- Notice your triggers: What people, places, or media tend to lead you astray? Can you make changes?
- Pray for guidance and strength. Even a simple prayer—“God, help me think good thoughts today”—can refocus your heart.
- Surround yourself with people who encourage your growth.
- Forgive yourself when you slip, and ask God for the strength to try again.
Conclusion: Living With a Pure Heart
Jesus’ teaching in Matthew 5:28 stretches us to grow—not just in what we do, but in who we are inside. When we invite God into our thoughts, we experience real transformation and deeper peace. It isn’t always simple, but you’re never alone. Together, we can support each other as we strive for loving, pure hearts.
