In this Healing School message, Justin He stresses that genuine belief in God's promises, such as healing, must be substantiated by observable actions, and recounts stories from Kenneth E. Hagin to demonstrate how individuals who acted on their faith received healing, while those who refused to act, citing inability or unbelief, remained unhealed. Justin challenges listeners to examine whether they truly believe their confessions by acting as if God's word is true, warning against blaming God or others for unmanifested healing and encouraging accountability and tangible steps to prove faith, such as making a list of actions that align with believing in one's healing.
