John 11:40 Meaning

38Jesus therefore again groaning in himself cometh to the grave. It was a cave, and a stone lay upon it.

39Jesus said, Take ye away the stone. Martha, the sister of him that was dead, saith unto him, Lord, by this time he stinketh: for he hath been dead four days.

40Jesus saith unto her, Said I not unto thee, that, if thou wouldest believe, thou shouldest see the glory of God?

41Then they took away the stone from the place where the dead was laid. And Jesus lifted up his eyes, and said, Father, I thank thee that thou hast heard me.

42And I knew that thou hearest me always: but because of the people which stand by I said it, that they may believe that thou hast sent me.
