Truth_b_known, those around him did see him in kingdom glory. It's called the transfiguration.
Jesus promised Judgment Day with his second coming. That obviously didn't happen at the transfiguration. So, the transfiguration is not the second coming.
Matthew 24:34 puts an expiration date of about 73 CE on Jesus prophecy. All of Matthew 24 was to be fulfilled before the generation that heard Jesus' words all died. It wasn't. Matthew 16:28 is evidence of this as Jesus said "some who are standing here will not taste death". Notice Jesus said only some would not taste death. So, Jesus was not speaking in terms of physical death versus an immortals soul. Some (at least 2 people) would still be alive to see Jesus return in his heavenly glory and pass judgment on the Earth. This is the reason why Paul wrote "Now to the unmarried and the widows I say: It is good for them to stay unmarried, as I do." Why get married if your marriage was going to be nullified with Jesus' second coming?
To say otherwise is to say "Jesus second coming is true, and since it hasn't happened yet, what he said must have some meaning other than the literally meaning."
