When Jesus Christ set up His method of healing in the world it was peculiar and distinct. The devil can manifest some other system, or man can evolve some other system and it may have power in a degree. But God has a particular method. Christ used it because it was divinely superior to every other, and would accomplish a result none other could.
No man ever lived in the world who ever caused the eye to grow in a child that had no eyes, or a man that was born blind to see. No man ever created a remedy in the world that would make a girl's leg to grow two inches, after she was seventeen years old, and had been born in that condition.
God demonstrates the superiority of His system, and of His power, and His divine remedy, in that it will accomplish in man what nothing else will.
John G. Lake
