Mark 5:21-34 - What is belief? What kind of faith actually heals a person? Actually saves a person? Being the Son of God, Jesus knows of the devastating, even lethal, effects of sin. As a result, His compassion flows out of Him wherever He goes. He also knows that there's a difference between physically healing someone in this life and spiritually healing someone for an eternity of life with Him. Similar faith is required for both, with the difference being what you're trusting God to do.
