How do we know Jesus is able to heal our spiritual ailments?

Throughout His ministry, Jesus performed numerous miracles that validated His identity as the Messiah, fulfilling Old Testament prophecies (Isaiah 35:5-6, Isaiah 42:6-7). These miracles, including the healing of the leper, were not only acts of compassion but also served as spiritual lessons illustrating God's saving grace (Matthew 11:4-5). Each healing pointed to the greater reality of spiritual healing that comes through faith in Him. Jesus demonstrated that He has authority over both physical and spiritual sickness, encouraging believers to place their trust in Him for both their temporal and eternal needs. The leper, who came in humility and faith, experienced this reality that Jesus could not only heal his leprosy but also cleanse him from the deeper ailment of sin.
