Jamieson, Fausset and Brown on John 11:6

6. When he heard he was sick, he abode two days still ... where he was--at least twenty-five miles off. Beyond all doubt this was just to let things come to their worst, in order to display His glory. But how trying, meantime, to the faith of his friends, and how unlike the way in which love to a dying friend usually shows itself, on which it is plain that Mary reckoned. But the ways of divine are not as the ways of human love. Often they are the reverse. When His people are sick, in body or spirit; when their case is waxing more and more desperate every day; when all hope of recovery is about to expire--just then and therefore it is that "He abides two days still in the same place where He is." Can they still hope against hope? Often they do not; but "this is their infirmity." For it is His chosen style of acting. We have been well taught it, and should not now have the lesson to learn. From the days of Moses was it given sublimely forth as the character of His grandest interpositions, that "the Lord will judge His people and repent Himself for His servants"--when He seeth that their power is gone (De 32:36).
