If i may offer something, in respect to your post.
The bible states about Jesus's assertions that he would be coming back "soon" and that certain other things would take place before "this generation" would pass away. But, these things still have not happened. Jesus says that there were some present who "will not have gone through all the towns of Israel, before the Son of man comes." (Mt 10:23) He also states that they would not "taste death before they see the Son of man coming in his kingdom." (Mt 16:28) None of that happened, and those people are all long dead.
