For they are life to those who find them, healing and health to all their flesh. God's Word is full of life. But, just like medicine from a doctor, God's Word must be ingested to be effective. But if you faithfully take it, you'll find it's the best medicine. The case is settled.
Healing can never pass away.
God is a Healer. He never changes. So healing will never cease. All things are possible. Healing from God is still available.
