What does the Bible say about healing through faith?

In the Gospel of Mark, we see the powerful example of a woman who had suffered from a blood issue for twelve years. Mark 5:34 highlights that it was her faith that led to her healing when she touched the hem of Jesus' garment. This incident illustrates the principle that faith in Christ, as the divine healer, is essential for receiving both physical and spiritual healing. The narrative teaches that we should approach Christ as needy sinners, trusting in His mercy and grace to remedy our deepest issues, especially sin.
