Matthew 5:28 from the King James Version (KJV) of the Bible reads, "But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart." This verse is part of Jesus' Sermon on the Mount, a well-known and influential passage in the Gospel of Matthew. It comes as a part of Jesus' explanation of the commandment against adultery and serves as a warning against the sin of lust.

The context of this verse is important in understanding its meaning. In the preceding verses, Jesus had been addressing the commandment against adultery, stating, "Ye have heard that it was said by them of old time, Thou shalt not commit adultery" (Matthew 5:27). Here, Jesus begins to expand on the deeper implications of this commandment, going beyond the outward act to address the thoughts and intentions of the heart. This is a consistent pattern in Jesus' teachings; he often exposed the inward motivations behind outward actions, emphasizing the importance of the heart's condition before God.

The verse addresses the issue of lust, specifically the act of looking at a woman with the intent to lust after her. In doing so, Jesus makes it clear that the sin of adultery is not limited to the physical act but can also occur in the heart and mind. This warning reflects the broader theme of Jesus' teachings on internal purity and righteousness, rather than mere adherence to external laws. It underscores the idea that sin begins in the heart and mind before it manifests in actions.

The symbolism in this verse is found in the concept of adultery, a breach of the marriage covenant. In Jewish culture, adultery was considered a serious offense, punishable by death, and often used as a metaphor for spiritual unfaithfulness to God. By equating lustful thoughts with the act of adultery, Jesus raises the moral standard even higher, emphasizing the importance of personal purity and faithfulness in one's heart.

The verse also serves as a call to humility and self-examination. It challenges individuals to consider their own inner thoughts and desires, recognizing the potential for sin even in the subtlest of intentions. By addressing the issue at its root, Jesus calls for a radical transformation of the heart, rather than merely external behavior modification.

In a broader theological context, this verse aligns with the New Testament theme of inner transformation through the power of the Holy Spirit. It underscores the need for a change of heart and mind, brought about through the indwelling of the Holy Spirit, rather than mere adherence to external rules and regulations.

Overall, Matthew 5:28 reflects Jesus' timeless message of righteousness, emphasizing the importance of inner purity and faithfulness. It challenges individuals to examine their motives and desires and calls for a fundamental change in the heart. Through its powerful and convicting message, the verse continues to be a reminder of the high moral standard set forth by Jesus and the need for personal transformation in the pursuit of righteousness.
