Do not be deceived…
Mat 3:1-2 In those days came John the Baptist, preaching in the wilderness of Judaea, And saying, Repent ye: for the kingdom of heaven is at hand.
Mar 1:14-15 Now after that John was put in prison, Jesus came into Galilee, preaching the gospel of the kingdom of God, And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel.
Luk 17:20-21 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: Neither shall they say, Lo here! or, lo there! for, beholdthe kingdom of God is within you.
So, "the time is fulfilled", the Kingdom of Heaven/God is; "at hand" and has been for over 2,000 years. However, the complete manifestation, in the earth, has not yet been apparent in Gods people as He has purposed it to be, to date.
