How do we know that Jesus heals all our diseases?

The healing that Jesus provides goes beyond physical ailments; it encompasses spiritual maladies as well. In Psalm 103:3, it is stated, 'Who forgiveth all thine iniquities, who healeth all thy diseases.' This passage assures us that God's promises include complete forgiveness and holistic healing. Jesus' earthly ministry featured many physical healings, but these acts served as signs of the greater spiritual healing He accomplishes in the new birth, covering all aspects of sin and spiritual infirmities we experience.
