Jesus didn't have a traveling sideshow. His miracles revealed spiritual truth. They weren't spectacles. His miracles were not disconnected from spiritual realities. There is no other way to understand the story, but to see that Jesus calls His elect, by His word, and they are made alive.
Wrong. The "spiritual truth" revealed is that Jesus is the resurrection and the life, not that unregenerate people are dead corpses!
Jesus heard about Lazarus being sick yet he stayed where he was for two additional days and then decided to go to Bethany. Why? Because he wanted to use Lazarus as an example of the resurrection. Jesus deliberately tarried so that Lazarus could die. In fact, Jesus told his disciples that Lazarus was asleep, they didn't understand he meant that Lazarus was DEAD. Even Jesus' disciples didn't grasp the alleged, "dead in sins" analogy.
So, if as you claim, that Lazarus is an analogy for people being spiritually dead why did Jesus not teach that very lesson? Why would he couch his words to his disciples to make them think that Lazarus was only sleeping?
If your analogy holds, why would Thomas say, "let us go there and die also?", i.e. Let us all go there and be dead in our sins?
11 After he had said this, he went on to tell them, “Our friend Lazarus has fallen asleep; but I am going there to wake him up.”
12 His disciples replied, “Lord, if he sleeps, he will get better.”
13 Jesus had been speaking of his death, but his disciples thought he meant natural sleep.
14 So then he told them plainly, “Lazarus is dead,
15 and for your sake I am glad I was not there, so that you may believe. But let us go to him.”
16 Then Thomas (also known as Didymus) "said to the rest of the disciples, “Let us also go, that we may die with him.”
40 Jesus says, “Did I not tell you that if you believe, you will see the glory of God?”
Note there is no "allow me to give you a new heart, to figuratively "make alive" your "dead in sin body", and then you can see the glory of God. No, it was, "believe and you will see the glory of God."
The lesson of Lazarus is not that people are "dead in sin", the lesson is that Jesus holds the literal power over death through the resurrection!
