How do we know the healing of the impotent man is true?

The story of the impotent man at the pool of Bethesda in John 5 serves as a profound display of Christ's healing power. When He commands the man to rise, take up his bed, and walk, the immediate restoration of the man's health attests to Christ's divine authority as the Son of God. This event not only signifies physical healing but also illustrates the deeper spiritual healing Christ offers. By addressing both physical and spiritual ailments, the narrative reinforces the belief in Christ’s complete power to heal and save, confirming His identity as the Messiah and the fulfillment of God's promises.
