Jamieson, Fausset and Brown on Mark 8:25

25. After that he put his hands again upon his eyes, and made him look up; and he was restored, and saw every man clearly--Perhaps the one operation perfectly restored the eyes, while the other imparted immediately the faculty of using them. It is the only recorded example of a progressive cure, and it certainly illustrates similar methods in the spiritual kingdom. Of the four recorded cases of sight restored, all the patients save one either came or were brought to the Physician. In the case of the man born blind, the Physician came to the patient. So some seek and find Christ; of others He is found who seek Him not.
