How do we know the name of Christ has healing power?

The healing power of the name of Christ is evident in Scripture as He is described as both the Physician of souls and the source of spiritual balm for afflicted hearts. Just as physical ointments possess the ability to heal wounds, Christ's name brings about spiritual restoration and cleansing. The use of His name in prayer and the proclamation of His promises result in the healing of guilt, shame, and despair, as seen in the examples of His miracles. The metaphor of ointment further emphasizes that His grace is potent, instantaneously transforming and renewing those who call upon Him in faith.
