Jesus restored Lazarus by the understanding that Lazarus had never died, not by an admission that his body had died and then lived again. Had Jesus believed that Lazarus had lived or died in his body, the Master would have stood on the same plane of belief as those who buried the body, and he could not have resuscitated it.

What does the Bible say about the state of Lazarus?
John 11:11-15, Jesus said, “‘Our friend Lazarus has fallen asleep; but I am going there to wake him up.’ His disciples replied, ‘Lord, if he sleeps, he will get better.’ Jesus had been speaking of his death, but his disciples thought he meant natural sleep. So then he told the plainly, ‘Lazarus is dead, and for your sake I am glad I was not there, so that you may believe.’”
Verse 17 says that Lazarus had been in the tomb for four days. The story continues with the discussion of his death, the fact that he would be stinking, and even that Jesus wept because Lazarus was dead.
Jesus said that Lazarus was “asleep,” but he meant Lazarus was dead. Paul also spoke of the dead as being “asleep” (1 Cor. 15:51), because in both cases they knew that the dead would rise back to life.
Jesus as God was the creator, and was certainly able to restore life to the dead, as will happen in the resurrection. To say Jesus would be unable to do so if He thought the person was really dead is to blaspheme Him.
The Bible says Lazarus was dead, and dead for four days. It says Jesus knew he was dead and even wept over the fact. It also says Jesus raised Lazarus from the dead knowing he was fully dead.
Mary Baker Eddy has written a lie contradicting the plain reading of Scripture. She is again proven to have been a false teacher.
