How do we know that Christ's healing includes spiritual healing?

In Acts 28, the physical illness of Publius's father symbolizes the spiritual sickness of humanity. Just as the father was unable to heal himself, sinners are incapable of addressing their spiritual disease—sin. Romans 3:10 confirms that none are righteous on their own, highlighting our need for the Great Physician. Through His sacrifice, Christ offers spiritual healing that brings eternal restoration and life. This healing is not just a one-time event but an ongoing process, as believers continually turn to Christ for strength and grace in their spiritual journey.
