I always wondered about a scenario where the people would be disappointed on Jesus.

Like, my life sucks. If Jesus comes back now, Ive done nothing with my life. Have really no expectations of afterlife rewards and so on.

Some people just dont like the idea of needing to be saved, or requiring evaluation of their savior to believe or having someone having ascendency over them, or worshipping someone and so fort. Im just the equivalent of a disciple, I dont love him very much, because I havent been forgiven much. But havent done any works or produced anything worth of mention.

This is mainly for the little children, children of pride of Gospel of Matthew. The publicans, pharisees, jews, illuminati and overal the elite who have preconceived notions of who Jesus was, what he achieved or didnt achieved or private historical records that may invalidate the belief on Jesus and so on...

So for this people, a new christ will be provided, maybe two or three, at the same time at different places, or in succession. Maybe intended to succeed, or to fail, to raise up or to cause to fall, to deceive or to reveal or both.
Lots of possibilities.

Of course most of the narratives you have are either provided by the elite, or specific churches or types of religions such as messianic shia, or protestants or seven day adventists and so on.

Rest assured that there is a plan by the Father, or Satan, or God, or Jesus or all of them and the angels and demons and stuff are all working on it.
