Matthew 9:12–13
While Jesus was eating, he heard this and said, “It is not the healthy who need a doctor, but the sick. Go and learn what this means: ‘I desire mercy, not sacrifice.’ For I have not come to call the righteous, but sinners.”
The most dangerous spiritual condition is when a person sins yet believes they are righteous. Someone who knows they are sick can seek help; someone who is sick but thinks they are well will refuse the physician and deny treatment. This describes the Pharisees’ stance when they saw Jesus eating with tax collectors and sinners. They could quickly spot others’ faults—who was unclean, who crossed the line, who did not belong at the table—but they lacked the self-awareness to see their own heart. They equated rule-keeping and religious offerings with health before God. Yet judgmentalism, pride, and an absence of compassion reveal a deep spiritual disease.
Jesus answers them with the image of a physician and patients. He comes to sinners because sin is a disease of the soul that must be healed. A good doctor does not hate the patient for being ill, nor does he leave the illness unaddressed. Likewise, God’s mercy welcomes sinners and leads them to repentance. Jesus’ words “I have not come to call the righteous, but sinners” do not imply that some people do not need salvation. Rather, some acknowledge their sickness, while others hide it behind religious appearance. Tax collectors knew their poor reputation; the Pharisees assumed they had no problem. Feeling righteous, they closed themselves to correction and rejected the work of God standing before them.
Then Jesus says, “Go and learn what this means: ‘I desire mercy, not sacrifice.’” This rebuke is sharp, especially coming to those who considered themselves experts in Scripture. They knew the texts but did not grasp God’s heart. Knowledge that does not change character creates spiritual pride. A person may worship regularly, give offerings, master doctrine, and serve actively, yet remain hard, unforgiving, and indifferent to the lost. Mercy becomes the litmus test of whether our religion centers on God or on our image. Offerings can be seen, knowledge can draw admiration, and ministries can be praised. Mercy, however, is often performed without spotlight; it requires humility and carrying another’s burden. There, the heart is revealed.
God is not abolishing worship or offerings; He rejects worship separated from obedience and compassion. Religious activity cannot substitute for a righteous life. We cannot cover bitterness with service, exchange honesty for offerings, or claim holiness because we do not commit another’s visible sins. The measure of righteousness is not comparison with worse people but conformance to the Father’s will.
Therefore, before diagnosing others’ spiritual illnesses, let Scripture examine us. Are we quick to belittle those with bad backgrounds? Do we consider ourselves more acceptable to God because of position, ministry, or theological knowledge? Do we keep religious rituals while refusing to forgive? Such attitudes reveal that we need the Physician as much as those we criticize. Experiencing God’s mercy should make us bearers of mercy. True mercy dares to name sin as sin while still opening a path to repentance. It does not humiliate to exalt oneself, but it helps the fallen to rise and return to God’s way.
