The extent of Christ's power to heal is put in as sweeping language. His power always covered fully the man's need, whatever that chanced to be. There was simply no limit. His healing met every need, and met it fully. It could not have been greater. Three words can be used: Christ healed instantly, perfectly, and permanently.
There is one exception frankly spoken of. Once, the healing went through two stages. First the man saw men "as trees walking," then "all things clearly." The interval of time involved was plainly so brief that, I think likely, the man himself would have gladly used the word "instantly."
Again that outstanding passage comes in. Its language could not be more graphic and adequate, and yet simple and brief. Matthew says "The multitudes wondered when they saw the dumb speaking, the maimed whole, and the lame walking, and the blind seeing."(Mat_15:31)
The extent of the power at work is as striking as the sweep of disease covered. There's a bubbling-over exuberance, an overflowing abundance. The crowds came to know that if they would "only touch the border of His garment" they would know the healing power in their body.
It says "power came forth from Him," as though it breathed out of His very presence. The ease of action, the abundance of power, and the frequency and extent of Christ's healing power stand in striking contrast to the Old Testament miracles.
And the effect on the crowds itself revealed the touch of God. "They glorified" God. There was an exuberant singing of praise to such a God. Even the curious crowds that came seeking sensation found a sort that sent them away with a hush in their hearts, and praises to God on their lips.
And, it is striking to note, that Christ gave this power to His disciples, unschooled and undisciplined as they were, yet devoted to Him.
Repeatedly they were sent out into the villages and country districts. And they returned with ringing voices and shining faces, telling of the power that had attended their activity. And usually special emphasis is laid on healing, and on the casting out of evil spirits.
