What does the term 'whole' mean in a spiritual context?

In the context of Matthew 9:12, those who are 'whole' are those who believe they are capable of achieving righteousness on their own and thus do not see their need for a physician—Christ. This self-perception can lead to spiritual blindness, preventing individuals from seeking the Savior. Recognizing our brokenness and need for Christ, unlike the self-sufficient, opens the door to true healing and salvation. Only those who acknowledge their spiritual deficiency can fully embrace the grace offered in Jesus.
