What does the Bible say about the need for a physician?

In Mark 2:15-17, Jesus identifies himself as the physician for the spiritually sick, stating, 'They that are whole have no need of a physician, but they that are sick.' This signifies that only those who acknowledge their sinfulness and need for healing can truly seek Christ. The scribes and Pharisees questioned why Jesus associated with publicans and sinners, showcasing their misunderstanding of the gospel. Jesus explains that his mission is to call sinners to repentance, underscoring the necessity of recognizing one’s own sinfulness to appreciate the need for his saving grace.
