How do we know Jesus can heal our spiritual sickness?

The Gospel illustrates that Jesus not only healed physical ailments but also addressed spiritual needs. He asks the paralyzed man at Bethesda, 'Will you be made whole?' (John 5:6), indicating that He is the source of true healing. This invitation to wholeness captures the essence of the gospel. Jesus came to call sinners to repentance and to offer them eternal life, as seen in John 5:39-40, where He points out that the Scriptures testify of Him, yet many refuse to come to Him to receive this life. This invites those who recognize their spiritual condition to turn toward Him, showing that faith in Christ is the means by which one receives healing of the soul.
