The answer is: Because the Pharisees criticised him for eating with publicans and sinners

Matthew 9 vs 12

In Matthew 9:12, Jesus’s statement, “They that be whole need not a physician, but they that are sick,” paints a vivid picture of His mission on Earth. This line emerges amidst a confrontation with the Pharisees, who couldn't fathom why a holy man would spend time with social outcasts like tax collectors (publicans) and sinners. It's almost as if Jesus thought, “These are the very people who need me the most!”

During His time, healing—the physical and spiritual kind—was crucial. Many saw illnesses as a direct link to sin and proximity to those labeled as “sick” often raised eyebrows. Yet, Jesus flips the narrative. By choosing to be among the poorest, the downtrodden, and those marginalized by society, He emphasizes a foundational truth: connection and compassion often transcend ritualistic piety.

Curiously, the term “physician” shows importance in the ancient world. Healer and community caretaker were seen as overlapping roles. In fact, Hippocrates, often called the father of medicine, emphasized the need for empathy in healer-patient relationships—exactly what Jesus contemplates when extending love to the “sick.”

This lesson reaches beyond the first-century context; it resonates today. It challenges us on how we choose to view and engage with those society often overlooks or even criticizes. The invitation remains: extend grace to those in need, recognizing our shared humanity. After all, are we not all somewhat “sick” in our own ways?
