For we have, we surely have, spiritual charms, even the Name of our Lord Jesus Christ and the Power of the Cross. This charm will not only bring the serpent out of his lurking places, and cast him into the fire (Acts 28:5), but even wounds it healeth. But if some that have said this Name have not been healed, it came of their own little faith, and was not owing to any weakness in what they said. For some did throng Jesus and press Him (Luke 8:44-45), and got no good therefrom. But the woman with an issue, without even touching His Body, but merely the hem of His garment, stanched a flux of blood of so long standing. This Name is fearful alike to devils, and to passions, and to diseases. In this then let us find a pleasure, herewith let us fortify ourselves. It was thus Paul waxed great, and yet he was of the like nature with ourselves, so the whole choir of the disciples.
