Matthew 5:28
But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
Matthew 5:28 (KJV)
Context
Matthew 5:28 is part of the Sermon on the Mount, where Jesus addresses the seventh commandment, “Thou shalt not commit adultery” (Exodus 20:14). He begins with “But I say unto you,” contrasting His teaching with the traditional understanding of the Law. While the commandment prohibited the physical act of adultery, Jesus extends its application to the inner thoughts and desires of the heart.
Meaning
In this verse, Jesus teaches that anyone who looks at a woman with the intent to lust after her has already committed adultery in his heart. The Greek text uses verbs indicating a deliberate, purposeful gaze, not merely an accidental glance. The phrase “in his heart” emphasizes that sin originates internally, not just in outward actions. Jesus equates lustful thoughts with the act of adultery itself, showing that God judges not only actions but also intentions.
This teaching raises the standard of righteousness. Jesus is not focusing on the act of looking or appreciating beauty but on entertaining lustful thoughts that objectify another person. The principle applies to both men and women, as the phrase “whosoever” indicates. Jesus uses strong language to emphasize the seriousness of this matter, highlighting the need for purity in both actions and thoughts.
Biblical connections
Jesus is referring to the seventh commandment given in Exodus 20:14, which originally addressed the physical act of adultery. He extends its application to the intentions and desires of the heart. This teaching is part of a broader passage (Matthew 5:27-30) where Jesus addresses adultery, lust, and the importance of radical measures to avoid sin. The following verses speak of cutting off or plucking out what causes sin, underscoring the seriousness of the matter.
Application
Guarding Our Thought Life: This verse reminds us to be vigilant about our thought life. We should strive to fill our minds with thoughts that are pure, honourable, and pleasing to God.
Accountability and Support: Engaging in open and honest discussions about this topic within trusted relationships can help individuals to be accountable and find support in their pursuit of purity.
The Role of God’s Grace: As believers, we are not left to our own efforts in achieving righteousness. We rely on God’s grace, seeking His help and guidance through prayer, studying His Word, and cultivating a relationship with Him.
Renewal and Transformation: As we pursue purity of heart, we should recognize that transformation is a lifelong process. Through the power of the Holy Spirit, we can experience renewal and growth, gradually aligning our thoughts, desires, and actions with God’s will.
Reflection
This verse prompts individuals to examine their thought life and intentions. It challenges believers to recognize the importance of cultivating pure thoughts, guarding against lustful desires, and treating others with respect and dignity. Righteousness extends beyond mere outward conformity to God’s commandments; it involves the transformation of the heart. Jesus’ teaching reveals that true righteousness goes beyond external compliance to the Law and reaches into the innermost being.
