Jesus established His Ekklesia, founded upon what Peter stated of Who Jesus IS. That is a spiritual Body of Christ. The Kingdom is yet to be revealed, except that Jesus Himself told the Pharisees ‘the Kingdom is at hand’ ... He is the central and most essential aspect of The Kingdom. But again, He told His disciples at the last supper: Luke 22:17Then he took a cup, gave thanks, and said, Take this and share it among yourselves, 18because I tell you, from now on I will never drink the product of the vine until the kingdom of God comes.
18 because I tell you, from now on I will never drink the product of the vine until the kingdom of God comes.
And i am not going to give a bunch of scripture to try and contradict it, as i do not know.
I only know that there is a lot of plain scripture which points to a spiritual return which many have been fortunate enough to have seen and many will see.
