Matthew 5:28 – “But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.”
An Extended Explanation of the Verse
In this verse, Jesus deepens the teaching on adultery by addressing the heart and thoughts, not just outward actions. He explains that lustful intent is equivalent to adultery in God’s eyes because sin begins in the heart. Jesus is not condemning natural attraction but rather the deliberate and unchecked dwelling on lustful thoughts, which distort God’s design for purity and faithfulness. This teaching highlights that righteousness is about more than behavior—it’s about the condition of one’s inner life.
Historical Context
In Jesus’ time, religious leaders focused heavily on outward compliance with the Law. They emphasized avoiding physical acts of adultery but often overlooked the internal attitudes that lead to sin. Jesus’ audience would have been familiar with this external focus, but His teaching about the heart would have been radical and challenging. By equating lustful thoughts with adultery, Jesus exposed the self-righteousness of those who believed they were righteous simply because they had not acted on sinful desires.
Theological Implications
This verse shows that God’s standard of holiness is not limited to actions but includes thoughts and intentions. It reminds us that sin is not just about what we do but also about what we allow to dwell in our hearts and minds. This teaching calls for a deeper dependence on God’s grace and the transforming power of the Holy Spirit to live a life of purity. It also emphasizes the value God places on honoring relationships and upholding His design for faithfulness.
Literary Analysis
The contrast between “you have heard” (v. 27) and “but I tell you” underscores Jesus’ authority to interpret the Law. The use of “has already committed adultery” emphasizes that sin begins long before physical actions take place. By focusing on the heart, Jesus shifts the emphasis from external observance to internal transformation, aligning with the broader themes of the Sermon on the Mount.
