Jesus already came (at lest for some)

[Fake Messiah]

This was to reference that John was a representative of who Elijah was.

Not according to Jesus. In Matthew 11:14 Jesus says J.B. is the Elijah. Not representative, but Elijah himself and yet in John 1:21 They asked him, “Then who are you? Are you Elijah?” He said, “I am not.” “Are you the Prophet?” He answered, “No.”
But I guess you know more then Jesus.

Christ is the one shepherd and the worlds Christians are His one flock.

Oh, too bad no one told this to Catholics and Protestants in Ireland they might stop killing each other over "right" Jesus. For sure then the massacre in Greysteel, at Halloween 1993 could have been avoided when Protestants bursted into a Catholic pub, shouted "trick or treat," and opened fire, killing 8 and wounding 13. Or all over Christian history where millions of people were killed by Christians because they were "wrong" Christians like the Cathari and the Waldensians with pope's famous blessing "Kill them all; God will know his own." and all those Catholic-Protestant wars, just the Thirty Years War in the 1600s, killed half the population of Germany. So this is one blatant lie you're telling.

When one is an eternal being 2000 years is less than a second.

Or maybe just a desperate to delude yourself in order to believe that Jesus was legit god. Like I told you he made many false prophecies like being in Earth for 3 days and nights and yet he did not. Or lying his ass off to the thief that tomorrow he will be with him in paradise when he is supposed to be in ground. I mean this is not just an ordinary Jesus lie like when he said that mustard seed is the smallest one in the world, but he is actually lying to the dying man, giving him false hopes. How much lower can you get from that.
Even Jesus himself he is a cheat. In Mark he simply asks 10:18. "Why callest thou me good? There is none good but one, that is God." Here we have a clear-cut statement by Jesus that his character is flawed and that he is not to be considered the model of propriety. We have it from his own mouth. What more could one want?
So no wonder he lies, like to the thief on the cross, or to the anyone around him like in John 7:8-10 he told some people to go to a feast and that he would not be going. The text states that he later went up, not in public, but in private. Or when he "predicted" in Matthew 17:12-13 that he will die in the same manner John the Baptist was killed. Needles to say one was beheaded in prison while the other one crucified.
