Man by nature is spiritually dead as Lazarus was physically dead, the point is the dead needs resurrection and its out of mans ability. The Illustration showed the Glory of God in giving life to the dead, that's why Jesus waited for him to die in his sickness Jn 11:38-44
39 Jesus 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.
40 Jesus saith unto her, Said I not unto thee, that, if thou wouldest believe, thou shouldest see the glory of God?
41 Then 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.
42 And 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.
43 And when he thus had spoken, he cried with a loud voice, Lazarus, come forth.
44 And he that was dead came forth, bound hand and foot with graveclothes: and his face was bound about with a napkin. Jesus saith unto them, Loose him, and let him go.
It took a miracle for him to be made physically alive, for the Glory of God, and likewise for those who are spiritually dead. Now I say this, as Lazarus was obviously one of Gods elect, so likewise those who are raised from spiritual death.
