Well Paul says he's coming again so I believe he will come again and he said that after Christ had risen from the dead. I don't know what period we're in, I don't have things divided up. All I know is that when Christ came back from the dead, he came in his power and glory and the kingdom of God came Just like Jesus said it would.
Luk 17:20 And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation:
Luk 17:21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
I live in that kingdom right now, heavenly Jerusalem. I do believe that this world will end and Christ will return but I have no understanding of how it goes down.... I wish I did.
