John 11:15

"And I am glad for your sakes." Why "for your sakes"? "Because I have forewarned you of his death, not being there, and because when I shall raise him again, there will be no suspicion of deceit." Seest thou how the disciples were yet imperfect in their disposition, and knew not His power as they ought? and this was caused by interposing terrors, which troubled and disturbed their souls. When He said, "He sleepeth," He added, "I go to awake him"; but when He said, "He is dead," He added not, "I go to raise him"; for He would not foretell in words what He was about to establish certainly by works, everywhere teaching us not to be vainglorious, and that we must not make promises without a cause. If any one ask, "How did the disciples imagine sleep? How did they not understand that death was meant from His saying, 'I go to awake him?' for it was folly if they expected that He would go fifteen stadia to awake him"; we would reply, that they deemed this to be a dark saying, such as He often spake to them.

And I am glad for your sakes that I was not there, that ye might believe; i. e. seeing My marvellous power of knowing a thing I have neither seen nor heard. The disciples already believed in Him in consequence of His miracles; so that their faith had not now to begin, but only to increase. That ye might believe, means, believe more deeply, more firmly.

Some have understood this place thus. I rejoice, He says, for your sakes; for if I had been there, I should have only cured a sick man; which is but an inferior sign of power. But since in My absence he has died, ye will now see that I can raise even the dead putrefying body; and your faith will be strengthened.
